Description

Technical Field

[0001] The present invention relates to the technical field of bridge vibration control, in particular to a stay cable lever mass damper. Background Art

[0002] As our infrastructure continues to improve, the construction technology for long-span cable-stayed bridges is becoming increasingly sophisticated. As the primary load-bearing component of a cable-stayed bridge, the cable-stays possess high flexibility and low damping. These characteristics make them highly susceptible to large vibrations in strong winds. Sustained, high-amplitude vibrations can easily cause fatigue damage to the cable itself and its associated structures, severely shortening its service life. This can also make pedestrians and vehicles on cable-stayed bridges feel unsafe.

[0003] In the prior art, a damper is often provided at a certain height at the end of the cable beam to suppress the vibration of the cable by increasing the additional damping.

[0004] In existing technology, for extremely long stay cables or stay cables with anchor plates, the damper installation height is generally required to be very high to ensure that the installation position meets basic requirements. If a conventional external damper is used, a large bracket is required to ensure the support rigidity of the damping device, resulting in excessive bracket investment and material waste.

[0005] Furthermore, existing damper designs primarily address in-plane vibration of stay cables. Actual bridge stay cables also experience out-of-plane vibration due to their vibration being perpendicular to the wind direction. When the external wind load is roughly parallel to the bridge axis, the cables can experience significant out-of-plane vibration. Existing lever-mass damping vibration reduction technology primarily addresses in-plane vibration and is insufficiently capable of controlling out-of-plane vibration of stay cables.

[0006] Therefore, it is very necessary to provide a cable-stayed lever damper to solve the above technical problems. Summary of the Invention

[0007] An embodiment of the present invention provides a lever mass damper for a stay cable, which can solve the problem that the existing lever mass damping vibration reduction technology in the related art basically solves the in-plane vibration and has insufficient control capability for the out-of-plane vibration of the stay cable.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0041] See also Figures 1 to 2 As shown, an embodiment of the present invention provides a cable-stayed lever mass damper, comprising a support 1, a connecting member 2, a main lever 3, a first damping device 4 and a second damping device 5, wherein the connecting member 2 is used to be connected to the cable; one end of the main lever 3 is fixedly connected to the connecting member 2, and the other end is rotatably connected to the support 1; the first damping device 4 is connected to the upper end of the main lever 3 for absorbing in-plane vibrations on the main lever 3; the second damping device 5 is connected to the lower end of the main lever 3 for absorbing out-of-plane vibrations on the main lever 3.

[0042] In this embodiment, it includes a support 1, a connecting member 2, a main lever 3, a first damping device 4 and a second damping device 5.

[0043] When the stay cable experiences in-plane vibration, the in-plane vibration is transmitted to the connector 2 due to the cable's connection to the connector 2. Since one end of the main lever 3 is fixedly connected to the connector 2, the in-plane vibration is transmitted from the connector 2 to the main lever 3. Since the first damping device 4 is connected to the upper end of the main lever 3, any in-plane vibration on the main lever 3 is absorbed by the first damping device 4.

[0044] Furthermore, when the stay cable experiences out-of-plane vibration, due to its connection to connector 2, the out-of-plane vibration is transmitted to connector 2. Since one end of main lever 3 is fixedly connected to connector 2, the out-of-plane vibration is transmitted from connector 2 to main lever 3. Since second damping device 5 is connected to the lower end of main lever 3, any out-of-plane vibration on main lever 3 is absorbed by second damping device 5.

[0045] At the same time, the connecting member 2 is connected to the oblique cable to transmit the vibration of the oblique cable to the connecting member 2, and the main lever 3 is connected to the connecting member 2 to transmit the vibration to the main lever 3. The first damping device 4 is connected to the upper end of the main lever 3 to absorb the in-plane vibration of the main lever 3; the second damping device 5 is connected to the lower end of the main lever 3 to absorb the out-of-plane vibration of the main lever 3. Through this application, both in-plane vibration and out-of-plane vibration can be absorbed.

[0046] In some embodiments, the support 1 is provided with a first ear plate 6 and a second ear plate 7;

[0047] The first damping device 4 includes an in-plane damper 8 and an in-plane lever 9, the in-plane damper 8 is rotationally connected to the second ear plate 7; the middle part of the in-plane lever 9 is rotationally connected to the main lever 3, one end of the in-plane lever 9 is rotationally connected to the first ear plate 6, and the other end is connected to the in-plane damper 8.

[0049] Wherein, the support 1 is provided with a first ear plate 6 and a second ear plate 7;

[0050] The first damping device 4 includes an in-plane damper 8 and an in-plane lever 9, the in-plane damper 8 is rotationally connected to the second ear plate 7; the middle part of the in-plane lever 9 is rotationally connected to the main lever 3, one end of the in-plane lever 9 is rotationally connected to the first ear plate 6, and the other end is connected to the in-plane damper 8.

[0051] Furthermore, because in-plane damper 8 is rotationally connected to second lug 7, and the middle portion of in-plane lever 9 is rotationally connected to main lever 3, one end of in-plane lever 9 is rotationally connected to first lug 6, and the other end is connected to in-plane damper 8, when in-plane vibration occurs, in-plane lever 9 rotates around main lever 3 and first lug 6, and then in-plane damper 8 rotates around second lug 7, absorbing the in-plane vibration.

[0052] In-plane damper 8 utilizes a viscous damper. This damper is based on the principle that fluid motion, particularly the resistance generated when fluid passes through an orifice, creates throttling resistance. It offers the advantages of high energy efficiency, no increase in structural rigidity, no change in the natural vibration period, and stable performance. Furthermore, it requires regular inspection based on the designed service life and design requirements, making it highly resistant to damage under normal use.

[0053] In some embodiments, it also includes a first deep groove ball bearing 10 and a second deep groove ball bearing 11. The in-plane lever 9 is rotatably connected to the first ear plate 6 through the first deep groove ball bearing 10; the middle part of the in-plane lever 9 is rotatably connected to the main lever 3 through the second deep groove ball bearing 11.

[0054] In this embodiment, it includes a support 1, a connecting member 2, a main lever 3, a first damping device 4 and a second damping device 5. The connecting member 2 is used to connect to the inclined cable; one end of the main lever 3 is fixedly connected to the connecting member 2, and the other end is rotatably connected to the support 1; the first damping device 4 is connected to the upper end of the main lever 3 for absorbing the in-plane vibration of the main lever 3; the second damping device 5 is connected to the lower end of the main lever 3 for absorbing the out-of-plane vibration of the main lever 3.

[0055] Wherein, the support 1 is provided with a first ear plate 6 and a second ear plate 7;

[0056] The first damping device 4 includes an in-plane damper 8 and an in-plane lever 9. The in-plane damper 8 is rotatably connected to the second ear plate 7. The middle portion of the in-plane lever 9 is rotatably connected to the main lever 3. One end of the in-plane lever 9 is rotatably connected to the first ear plate 6, and the other end is connected to the in-plane damper 8.

[0057] It also includes a first deep groove ball bearing 10 and a second deep groove ball bearing 11. The in-plane lever 9 is rotatably connected to the first ear plate 6 through the first deep groove ball bearing 10; the middle part of the in-plane lever 9 is rotatably connected to the main lever 3 through the second deep groove ball bearing 11.

[0058] At the same time, since the in-plane lever 9 is rotationally connected to the first ear plate 6 via the first deep groove ball bearing 10, the middle portion of the in-plane lever 9 is rotationally connected to the main lever 3 via the second deep groove ball bearing 11. Deep groove ball bearings primarily bear radial loads, but can also bear both radial and axial loads. When they bear only radial loads, the contact angle is zero. When the deep groove ball bearing has a large radial clearance, it has the performance of an angular contact bearing, can withstand large axial loads, and has a very low friction coefficient. Therefore, the rotation of the in-plane lever 9, the first ear plate 6, and the main lever 3 can be effectively transmitted via the first deep groove ball bearing 10 and the second deep groove ball bearing 11.

[0059] In some embodiments, a first spherical bearing 12 and a second spherical bearing 13 are further included. The in-plane lever 9 is rotationally connected to the in-plane damper 8 through the first spherical bearing 12 , and the in-plane damper 8 is rotationally connected to the second ear plate 7 through the second spherical bearing 13 .

[0060] In this embodiment, since the spherical bearing can withstand a larger load, the in-plane lever 9 is rotatably connected to the in-plane damper 8 via the first spherical bearing 12, and the in-plane damper 8 is rotatably connected to the second lug 7 via the second spherical bearing 13, which can effectively improve the service life.

[0061] In some embodiments, the support 1 is provided with a third ear plate 14;

[0062] The second damping device 5 includes an out-of-plane damper 15, an out-of-plane link 16 and an out-of-plane lever 17. The out-of-plane damper 15 is rotatably connected to the middle part of the main lever 3; one end of the out-of-plane link 16 is rotatably connected to the bottom of the main lever 3; one end of the out-of-plane lever 17 is rotatably connected to the out-of-plane link 16, and the other end of the out-of-plane lever 17 is rotatably connected to the out-of-plane damper 15, and the middle part of the out-of-plane lever 17 is rotatably connected to the third ear plate 14.

[0063] In this embodiment, the out-of-plane damper 15 is rotationally connected to the middle portion of the main lever 3, one end of the out-of-plane link 16 is rotationally connected to the bottom portion of the main lever 3, one end of the out-of-plane lever 17 is rotationally connected to the out-of-plane link 16, the other end of the out-of-plane lever 17 is rotationally connected to the out-of-plane damper 15, and the middle portion of the out-of-plane lever 17 is rotationally connected to the third lug 14. When out-of-plane vibration occurs, the out-of-plane vibration of the main lever 3 causes the out-of-plane link 16 to swing, which transmits the out-of-plane vibration to the out-of-plane lever 17. The out-of-plane lever 17 then transfers the out-of-plane vibration energy to the out-of-plane damper 15, which absorbs the out-of-plane vibration energy.

[0064] The out-of-plane damper 15 is a viscous damper.

[0065] In some embodiments, it also includes a third deep groove ball bearing 18, a fourth deep groove ball bearing 19 and a fifth deep groove ball bearing 20.

[0066] In this embodiment, the deep groove ball bearing has the performance of an angular contact bearing when the deep groove ball bearing has a large radial clearance, can withstand a large axial load, and the friction coefficient of the deep groove ball bearing is very small. The rotation of the out-of-plane link rod 16, the out-of-plane lever 17 and the third ear plate 14 is effectively transmitted through the third deep groove ball bearing 18, the fourth deep groove ball bearing 19 and the fifth deep groove ball bearing 20.

[0067] In some embodiments, a third spherical bearing 21 and a fourth spherical bearing 22 are further included. The out-of-plane lever 17 is rotationally connected to the out-of-plane damper 15 through the third spherical bearing 21 ; the out-of-plane damper 15 is rotationally connected to the main lever 3 through the fourth spherical bearing 22 .

[0069] In some embodiments, the connecting member 2 includes a cable clamp 23, a connecting rod 24 and a fifth joint bearing 25, the cable clamp 23 is used to connect to the inclined cable; the connecting rod 24 is rotationally connected to the main lever 3; the cable clamp 23 is rotationally connected to the connecting rod 24 through the fifth joint bearing 25.

[0070] In some embodiments, an outer frame 26 is provided on the support 1 .

[0071] In some embodiments, an embedded plate 27 is connected to the bottom of the support 1.

[0072] In this embodiment, the embedded plate 27 is provided in the bridge deck to better fix the support 1 on the bridge.
