    [0001] FIELD OF THE INVENTION The present invention relates to the vibration damping techniques that cables used to support the structures undergo. It applies in particular to bridge cable stays. The cables vibrate especially because of climatic actions such as wind, rain or frost, but also because of traffic on the structure. In order to dampen these vibrations, various types of device have been proposed. In a first type of damping device, the vibration damping is provided by a so-called internal damping device, that is to say by dampers arranged directly between a cable of the structure and another element of the supported structure of this structure, such as a tube attached to the supported structure (a bridge deck for example) and containing the lower part of the cable (see for example FR 2 859 260 A1). This type of device however reaches its limits when the cables become very long. A second type of so-called external device is then used and arranged between the cable to be damped and the deck of the bridge. In particular, in cable configurations of great length, it is known to use damping devices comprising a support for example T-shaped or A fixed to the deck of the bridge in question and on which are fixed the ends of linear dampers. The opposite ends of these dampers are attached to the cable to be damped via a collar through which the vibrations of the cable are transmitted. Devices of this type are adapted to effectively dampen the vibrations of cables of great length. However, they also have disadvantages. Indeed, the deflection of the very long cables induced by the vibrations is important, which requires the availability of shock absorbers having a large stroke and extension of a support of significant dimensions. This size of the support is problematic insofar as the space available on the deck is limited, which can lead to a conflict with the templates for pedestrians and vehicles on the bridge. An object of the invention is to improve this type of device for cables of great length. The invention relates to a vibration damping device of a cable, the device comprising: - a support, - at least a first damper for damping the vibration of the cable, the first damper comprising a first element and a second member being telescopically moveable relative to each other, the second member being adapted to be attached to the cable, the first member having a distal end and a proximal end relative to the cable, and - an arranged fastener on the support for fixing the first damper to the support, the attachment being fixed to the first damper at a location along the first damper located away from the distal end of the first member towards the proximal end. Due to the arrangement of the first damper relative to the support, the space requirement, and in particular the length of the damper, is a less dimensioning factor of the support. The dimensions of the support, and in particular its width, can therefore be reduced relative to the support of the type of device described above. According to another aspect of the invention, said location is located at a distance from the distal end of the first element of the first damper greater than or equal to 25%, and preferably greater than or equal to 50% of the length. of the first element. According to another aspect of the invention, the first member is a body of the first damper and the second member is a rod telescopically movable relative to the body, the attachment 15 being fixed to the first member. According to another aspect of the invention, the first element is a rod of the first damper and the second element is a body of the first damper, the rod being movable telescopically relative to the body. According to another aspect of the invention, the attachment comprises uprights, a plate pivotally mounted on the uprights around a first axis, the plate comprising a central passage in which the first damper is arranged, the first damper being mounted in the central passage pivotally relative to the plate about a second axis. According to another aspect of the invention, the attachment comprises journals carried by one of the plate and the first damper and complementary receiving ports carried by the other one of the plate and the first damper, the first damper being fixed to the plate by cooperation of the journals and the receiving orifices. According to another aspect of the invention, in a use configuration in which the support is fixed to a receiving structure and the first damper is fixed to the cable and the support, the first damper is inclined with respect to a vertical plane in which the cable extends. According to another aspect of the invention, the support comprises a recess in which the attachment is arranged and through which the or each first damper is arranged. According to another aspect of the invention, the recess comprises a central surface and at least one inclined surface oriented away from the attachment and located directly above the first damper. According to another aspect of the invention, the device further comprises at least one second damper for damping the vibrations of the cable, the second damper comprising a first element and a second element telescopically displaceable relative to one another. at the other, the second element being intended to be fixed to the cable, said first element being fixed to the support by a second fixing. According to another aspect of the invention, the second attachment is fixed to the first element of the second damper at a distal end of the first element of said second damper with respect to the cable. According to another aspect of the invention, the or each second damper extends in a vertical plane in which the cable extends. According to another aspect of the invention, the second attachment is attached to the second damper at a location along the first member of the second damper located away from the distal end of the first member. According to another aspect of the invention, in a use configuration in which the support is fixed to a receiving structure and the second damper is fixed to the cable and the support, the second damper is inclined relative to a vertical plane in which the cable extends. The invention also relates to a cable-stayed bridge comprising at least one pylon, an apron, cable stays consisting of cables extending obliquely between the pylon and the deck to support the deck, and at least one damping device. as defined above mounted between a cable and the apron. The invention will be better understood on reading the detailed description which follows, given solely by way of example and with reference to the appended figures, in which: FIG. 1 is a schematic illustration of a bridge with stay cable according to the invention; Figure 2 is a schematic illustration of a longitudinal view of a damping device according to the invention; - Figure 3 is a schematic illustration of a transverse view of a damping device according to the invention; Figure 4 is a schematic illustration of a first damper of a damping device according to the invention; - Figure 5 is an illustration of a fastening means for attaching a first damper to a support of the damping device according to the invention; Figure 6 is an illustration of a second damper and securing means of the second damper in a damping device according to the invention; Figure 7 is an illustration of a damping device according to a variant of the invention; and Figures 8a and 8b illustrate a damping device according to another variant of the invention. The invention is described below in its non-limiting application to cable-stayed bridges. The cables that are to dampen the vibrations are then the guys. These vibrations are for example due to the passage of vehicles on the bridge in question, wind, etc. Figure 1 illustrates a cable-stayed bridge 2 according to the invention. The bridge 2 comprises pylons 4, an apron 6 and shrouds 8 extending between one of the towers 4 and the apron 6 to support the deck 6. [0026] One or more shrouds 8 are equipped with a 10 of the invention, hereinafter device 10. The device 10 extends substantially transversely to the corresponding shroud 8 between a point of attachment P of the strut 8 located near its low anchorage (for example a few% of the total length of the stay 8) and the deck 6. [0027] Referring to Figure 2, the device 10 is fixed to the stay 8 at the point of attachment P by means of a collar 12 enclosing the stay 8 and wherein damping ends of the device 10 described below are received. The device 10 comprises a support 14, first dampers 16 and attachment means 18 of the first dampers 16 to the support 14. The device 10 further comprises second dampers 20 and attachment means 22 of the second dampers 20 to support 14. [0029] Support 14 is also known as a frame. Referring to Figures 2 and 3, the support 14 fixed at its lower end to the deck 6 of the bridge 2. Advantageously, the support 14 is immobile with respect to the deck 6. [0030] The support 14 extends substantially in a plane . The plane of the support is preferably substantially orthogonal to the direction of the stay 8. However, other orientations are possible. In particular, in some embodiments, the support 14 extends substantially orthogonally to the deck 6 and is not transverse to the stay 8, the latter being inclined with respect to the deck 6. In practice, the support 14 can be arranged on the apron 6 so that it is between a position in which it is substantially orthogonal to the deck 6 and a position in which it is substantially orthogonal to the stay 8. The support 14 has a generally V shape. and has two branches. The branches are of respective different lengths. The longest branch, hereinafter branch 24A, has a free end 26 offset laterally relative to the portion of the stay 8 which overhangs it. The first dampers 16 are fixed at this free end 26 via the fastening means 18. For this purpose, the free end 26 comprises a recess 28 (FIG. 5) in which the fastening means 18 are arranged. and through which the first dampers 16 are arranged. Referring to Figure 5, the recess 28 comprises for example a flat central surface 28C, and two inclined surfaces 281 on either side of the central surface 28C and located vertically above the first dampers 16. These inclined surfaces 281 are oriented away from the fastening means 18. As described in more detail below, the presence of these inclined surfaces 281 makes it possible to increase the angular deflection of the first dampers when they are caused to pivot relative to each other. to the support 14. [0033] The shortest branch of the support 14, hereinafter branch 24B (FIGS. 2 and 3), has a free end located substantially perpendicular to the stay 8 and at the level of which the second shock absorbers 20 In some embodiments, the support 14 further comprises a frame 30 (Figure 3) extending between the two legs 24A, 24B. This chord is for example in the form of a rod disposed substantially horizontally and anchored in the branches at its ends. The frame 30 provides greater rigidity to the branches urged by the dampers 16, 20 and 20 thus improves the overall stiffness of the support offered to the damping device by the support 14. The support 14 is made from a material having a good mechanical strength and good resistance to corrosion, and / or has a surface treatment against corrosion. Advantageously, the support 14 is made from steel. [0036] With reference to FIGS. 2 to 5, the first dampers 16 are preferably linear dampers. For example, the first dampers are cylinders, such as hydraulic cylinders, and dampen the vibrations of the stay 8 by viscous damping. In the embodiment illustrated by these Figures, the device 10 comprises two first dampers 16. The first dampers 16 are arranged parallel to each other. In addition, they extend substantially transversely to the stay 8. The first dampers 16 are also inclined relative to the vertical plane of the stay 8 in the use configuration of the device 10, in which the support 14 is fixed to the deck 6 which forms a receiving structure of the support 14, and in which the first dampers 16 are fixed to the collar 12 enclosing the stay 8. By "inclined relative to the vertical plane of the stay 8" is meant here that the first shock absorbers extend in a direction forming a significant angle with the vertical plane of the stay 8. With reference to FIG. 4, each first damper 16 comprises a first member 32 and a second member 34 telescopically movable relative to each other. to the other. For example, the elements 32 and 34 slide relative to each other. Thus, these elements slide for example one into the other. The first element 32 is fixed to the support 14, and the second element 34 is fixed to the stay 8 via the collar 12. These two elements 32, 34 correspond in practice to one of a body, or cylinder, the first damper 16 and a rod of this first damper. The following description will be made in a nonlimiting manner in the case where the first element 32 corresponds to the body and the second element corresponds to the rod. The body 32 is substantially cylindrical. The body 32 comprises a distal end 32D and a proximal end 32P relative to the stay 8 to which the device 10 is associated. In addition, the body 32 comprises two pins 36 forming part of the fastening means 18. These pins are in the form of radial projections of generally cylindrical shape. These pins 36 are disposed on either side of the body 32 on the same radial axis. The journals 36 are disposed at a location along the body 32 located away from the distal end 32D and toward the proximal end 32P, or at the proximal end 32P itself. In other words, the journals 36 are at an intermediate location along the body 32, or at the proximal end 32P. Preferably, the journals 36 are located at a distance from the distal end 32D greater than or equal to 25% of the length of the body 32, and advantageously greater than or equal to 50% of this length. In the example of Figure 4, they are located at about 90% of this length. Referring to Figure 4, the rod 34 is movable telescopically relative to the body. For example, the rod 34 is inserted into the body 32. The rod 34 is fixed at one end to a piston (not shown) movable in the body 32 and via which the viscous damping of the displacements 25 of the rod 34 is set. artwork. At its other end, the rod 34 is engaged in the collar 12. More specifically, the rod 34 comprises a head 38 provided with an orifice 40 receiving an axis 42 (Figure 3) of the collar 12 around which the rod 34 can rotate. [0041] With reference to FIG. 5, the fastening means 18 comprise a gimbal fastener 44 allowing the rotation of the first dampers 16 considered with respect to the support 14 along two orthogonal axes. The attachment 44 is arranged on the support 14. The attachment 44 comprises a base 46 fixed on the central surface 28C of the recess 28, and two uprights 48 fixed perpendicular to the base 46 facing one another . The base and the uprights are common to the first dampers 16. The fastener 44 also comprises, for each first damper 16, a plate 50 with pins 52 provided with a central passage 55 in which the body 32 of the damper 16 considered is engaged. The central passage 55 has larger dimensions than the section of the body 32, so that the body 32 is not held stationary by the edges of the central passage 55. As described hereinafter, this allows the relative rotation of the body 32 relative to the plate 50 in the passage 55. The plate 50 is fixed to the uprights 48 by its two cylindrical pins 52 extending coaxially from one and the other of two opposite slices of the plate 50, allowing the rotation of the plate 50 about an axis X. This axis X corresponds to the direction in which the journals 52 extend. The plate 50 further has two coaxial receiving ports 54 in each of which one of the pins 36 of the body 32 of the first damper 16 is movably accommodated (only one orifice 54 is shown in FIG. 5). These orifices 54 are arranged facing one another in the one and the other of the slices of the plate 50 which are not facing the uprights 48. These orifices 52 allow the rotation of the first damper 16 around a Y axis (corresponding to the axis of the orifices 54) substantially orthogonal to the axis X. This axis Y is substantially parallel to the uprights 48. [0045] With reference to FIG. 6, the second dampers 20 are advantageously dampers linear. For example, the dampers 20 are cylinders, such as hydraulic cylinders. The second dampers 20 extend substantially transversely to the associated guy 8. In addition, they extend substantially in the vertical plane of the associated guy 8. Each second damper 20 comprises a first element 56 and a second element 58 20 telescopically movable relative to each other. As for the first dampers, these first and second elements correspond to a body or a rod of the second damper. The following description is made in the non-limiting case in which the first element 56 corresponds to the body and the second element 58 corresponds to the rod. The body 56 has a generally cylindrical shape. In addition, it comprises a distal end 56D and a proximal end 56P with respect to the stay 8 and at which a passage opening 60 of a fixation axis of the fixing means 22 is arranged. [0048] The rod 58 is substantially identical to the rod 34 of the first dampers 16. It comprises an end fixed on a piston (not shown) movable in the body 56, and at its other end, a head 62 provided with a passage 64 for receiving an axis 42 of the collar 12. [0049] Still with reference to FIG. 6, the fixing means 22 comprise, for each second damper 20, an attachment pin 66 received in the orifice 60 of the body 56 of the second damper 20 corresponding. In addition, the fastening means 22 comprise a yoke 68 in which the fastening axis or pins 66 of the first shock absorber (s) are received. This yoke 68 is fixed to the support 14 at the end of the short branch 24B. Preferably, the yoke 68 is fixed to the support 14 by means of an axis 70 substantially orthogonal to or to the fastening pins 66. The fastening means 22 thus define a cardan fastener permitting the rotation of the second damper 20 by ratio to two orthogonal axes. As described in more detail below, this allows the second dampers to accompany the longitudinal displacements of the point P of the stay-cable 8, for example because of the thermal expansions of the latter, and to accompany the displacements of the point P in parallel with the plane of Figure 3 without the second dampers 20 are bent. The operation of the device 10 will now be described. During operation of the device 10, the stay 8 is subject to vibrations and expands under the effect of temperature variations. These vibrations and dilations result in displacements of the attachment point P both transversely to the stay 8 and longitudinally. These vibrations and displacements of the point of attachment P are communicated to the device 10 by means of the collar 12 to which are fixed the free ends of the rods 34 and 58 of the first and second dampers 16, 20. The displacements of the point P transversely to the stay induce a displacement of the rods 34, 58 in the body 32, 56 of the corresponding damper. The energy of these displacements is then dissipated in the corresponding damper by viscous damping. In addition, when the attachment point P moves longitudinally, the dampers 16, 20 pivot relative to the support 14 according to the axes of rotation authorized by the corresponding fastening means 18, 22 and thus follow the movements of the point. P without flexing. In particular, the first 20 dampers 16 pivot in the recess 28. The rotation of the rods 34, 58 of the dampers 16, 20 relative to the collar 12 also limits the bending applied to the dampers during the movements of the point of attachment P. 0053] The damping device 10 according to the invention has many advantages. In particular, the fixing of the first dampers at a location along these dampers situated away from the distal end of the first element makes it possible to reduce the size of the support. In fact, the length of the dampers is then an insignificant criterion for the support, unlike a configuration in which the damper is fixed to the support at the distal end of the first element 32. This arrangement reduces the space occupied by the support at the deck, which limits the inconvenience to the movement of vehicles and pedestrians that the support 30 could generate. This is all the more marked as the location of the attachment of the dampers to the support is remote from the distal end of the first elements 32 of the dampers relative to the stay they are intended to damp. In addition, this is particularly advantageous when the first dampers are inclined relative to the vertical plane in which the stay extends substantially. In addition, the arrangement of the second dampers substantially in line with the associated stay 8 contributes further to reduce the size of the device 10, in particular its lateral dimensions. Advantageously, in order to take advantage of this small lateral space, the support 14 is fixed at the deck 6, the branch 24B of the support being oriented towards a roadway C (illustrated in FIG. 3) of the bridge 2 on which vehicles run, the branch 24A being oriented away from this road. As illustrated in FIG. 3, the device thus allows the pedestrians to pass on the apron, for example between the support 14 and the edge of the deck, while not impeding the traffic on the roadway C. [0056] The embodiments described and discussed above are illustrations of the present invention. Various modifications can be made without departing from the scope of the invention which emerges from the appended claims. In particular, the device has been described as comprising two first dampers 16 and two second dampers 20. Alternatively, the device 10 comprises a single or more than two first dampers 16. In addition, in some embodiments, regardless of the number 15 of first dampers 16, the device 10 comprises one or more second two dampers 20. [0058] Furthermore, the pins 36 have been described as being carried by the first dampers 16. However, in a variant, the pins are worn. by the plate 50 and the orifices 54 are carried by the first dampers 16. [0059] In addition, the attachment 44 has been described as comprising a base 46 fixed to the support at the central surface 28C. However, alternatively, the base 46 is fixed to a side wall 28P of the recess 28. In another variant, the attachment 44 is devoid of base 46 and is fixed to the support 14 by its uprights 48. [0060] Moreover, the base 46 and the uprights 48 have been described as being common to the first shock absorbers 16. In a variant, the fastening means comprise, for each first shock absorber, amounts fixed to the support, or amounts and a base fixed to the support. In addition, in some embodiments, the recess 28 comprises a single inclined surface 281. In a variant, the recess 28 also or alternatively comprises vertical inclined surfaces 28V formed in the side walls of the recess 28 (FIG. dotted on Figure 5). These vertical inclined surfaces 28V are oriented away from the fastening means 18. They thus make it possible to increase the angular deflection of the first dampers when they pivot about the Y axis, in the same way as the inclined surfaces 281. allow to increase the angular deflection of the first dampers around the axis X. Furthermore, the second dampers 20 have been described as extending transversely to the stay 8 and substantially in the vertical plane of the stay 8. However, with reference to Figure 7, alternatively, the second dampers 20 have a similar arrangement to those of the first dampers 16. More specifically, the support 14 is substantially symmetrical with respect to a plane.
    [0002] The support 14 is for example arranged on the apron so that this plane of symmetry corresponds substantially to the vertical plane of the stay 8 in the use configuration of the device 10. The branch 24B has the same length as the branch 24A and also has at its end a recess 28 similar to that of the branch 24A. The second dampers 20 are received in this recess 28 of the branch 24B and are fixed thereto via the fastening means 22. The second dampers 20 are fixed on the branch 24B at a location along their body 56 located at a distance of the distal end 56D of this body and towards the proximal end 56P. They are also inclined relative to the vertical plane of the stay 8. The fastening means 22 have a cardan structure similar to the structure of the fastening means 18 described above, and allow the relative rotation of the second dampers 20 relative to the support 14 along two orthogonal axes. In addition, the plane in which the support 14 extends may be orthogonal to the vertical plane of the stay. Alternatively, the plane of the support may have other orientations relative to the vertical plane of the stay, that is to say that the support 14 can be fixed on the deck so that it is pivoted on itself and that the support plane is not orthogonal to the vertical plane of the stay. Furthermore, the fastening means 18 have been described as comprising a universal joint 20 allowing a rotation of the first dampers 16 relative to the support 14 along two orthogonal axes. Alternatively, the fastening means 18 allow the rotation of the first dampers only around a single axis. For example, the plate 50 is fixed immovably to the uprights 48 of the fastener 44, or the body 32 is fixed rigidly to the corresponding plate 50. [0066] In another variant, the attachment 44 is formed by an elastic ball joint integral with the body 32 and intended to cooperate with cavities formed in the walls of the recess 28 of the support 14. This ball also allows the rotation of the first damper 16 corresponding to the two orthogonal axes X and Y described above. As before, the ball is attached to the body 32 of the first damper 16 corresponding to a location along the body 32 located away from the distal end 32D of the body. In other embodiments, the second dampers 20 are disposed in the vertical plane of the stay 8 and transversely thereto, but are fixed to the support 14 not by their distal end (rear), but to a location along the body located away from their distal end, as for the first dampers 16. In such a variant, the branch 24B is longer than in the embodiment of Figures 2 and 3, and its end free end is located above the stay 8. This end is provided with a recess 28 similar to that of the branch 24A wherein the fastening means 22 are arranged and through which the second dampers 20 are received. The fastening means 22 are similar to the fastening means 18 described above and 5 comprise a universal joint allowing rotation of the second dampers relative to the support 14 along two orthogonal axes. Furthermore, the description has been given above in the case where the first element 32 of the dampers corresponds to the body of these dampers, and the second element 34 corresponds to their rod. However, other embodiments are possible. Alternatively, with reference to Figures 8a and 8b, for at least one first damper 16, the second member 34 corresponds to the body of the damper and the first member 32 corresponds to the rod. The first damper 16 further comprises a jacket 32F in which the rod 32 is received. In this embodiment, the first damper 16 (or possibly all or part of the different first dampers) is fixed to the support 14 via the jacket 32F in which the rod 32 is received. The liner 32 has a generally cylindrical shape arranged coaxially with the rod 32 and the body 34. The liner 32F has a distal end (with respect to the stay 8) which is closed, and a proximal end emerging for the insertion of the rod 32. The distal end 32D of the rod 32 is attached to the distal end of the jacket 32F, that is to say the bottom of the jacket 32F.
    [0003] This attachment is for example made by embedding. The jacket 32F is further secured to the support 14 at the branch 24A in the same manner as the body in the embodiments described above. In other words, the jacket 32F is fixed to the support 14 by a universal joint such as the attachment 44. This attachment is at a location along the damper which is located away from the distal end 32D This fastener 44 is fixed in a recess of the branch 24A and comprises, for example, pins and corresponding orifices carried by one and the other of a plate of the attachment 44 and the sleeve 32F, the tray itself being pivotally mounted on the amounts of the fixation about an axis orthogonal to that around which the rotation of the sleeve 32F relative to the plate operates. Without this being its main function, the presence of the jacket 32F has the effect of protecting the rod 32 from mechanical and climatic aggressions. Advantageously, a part of the body 34 is also arranged in the jacket 32F, which extends the protection conferred by the jacket 32F to this part of the body 34. In this configuration, to avoid stagnation and the accumulation of runoff water or For condensation purposes, a movable guard, such as, for example, a flexible bellows sleeve (not shown) may be provided on the body 34 at the proximal end of the jacket 3033803 12 32F. Alternatively or in parallel, one or more drainage holes may be made at the lower end of the jacket 32F. In some embodiments, the embodiments described above and technically compatible with each other are combined.
