Description

Technical Field

[0001] The invention relates to the technical field of vibration control, in particular to a hydraulic and flywheel inertial damping combined vibration reduction device. Background Art

[0002] In application scenarios such as super-high buildings and long-span bridge structures, vibration reduction devices are usually used to dissipate energy and reduce vibration in order to avoid structural safety hazards and economic losses caused by large vibrations. For example, when reducing vibrations on the main beam of a bridge, a vertical damper is set on the steel beam near the middle tower to increase the vertical vibration damping ratio, which has a significant effect on reducing wind-induced vibrations. When the main beam undergoes vortex vibrations of various modes, the stiffening beam at the damper will undergo vertical displacement, causing relative movement at both ends of the damper fixed on the bracket. The damper consumes the vibration energy of the stiffening beam, thereby achieving the purpose of reducing the vibration of the stiffening beam.

[0003] Relevant research has shown that inertia, as a mechanical unit, combined with damping, can improve the vibration reduction efficiency of the vibration damper and improve the control performance of the vertical vortex vibration of the main beam. However, vertical dampers containing inertia elements are rare. By combining related technologies, viscous damping and hydraulic inertia can be combined to obtain a high-performance vibration reduction device. However, there is a coupling effect between hydraulic inertia and viscous damping, which makes the inertia coefficient smaller than the damping coefficient, the inertia effect is insufficient, and the improvement in vibration reduction efficiency is not obvious.

[0044] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the 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 creative work are within the scope of protection of the present invention.

[0045] Figure 1 A schematic diagram of the structure of a hydraulic and flywheel inertial damping combined vibration reduction device in one embodiment of the present invention is shown; Figure 2 A schematic structural diagram of a piston and a spiral conduit in one embodiment of the present invention is shown.

[0046] Reference Figure 1 and Figure 2 The embodiment of the present invention provides a hydraulic and flywheel inertial damping combined vibration reduction device 100, which includes a cylinder 110, a piston 120, a spiral conduit 130, a first connecting member 140, a flywheel 150 and a second connecting member 160. The cylinder 110 has a first accommodating chamber A, in which a viscous fluid is contained. The piston 120 is disposed in the first accommodating chamber A and divides the first accommodating chamber A into two sub-chambers. The piston 120 is provided with a piston hole 120a connecting the two sub-chambers. The spiral conduit 130 connects the two sub-chambers. The first connecting member 140 is connected to the piston 120 and is at least partially located outside one end of the cylinder 110 to drive the piston 120 to move linearly in response to vibration. The flywheel 150 is transmission-connected to the piston 120 so that the piston 120 can drive the flywheel 150 to rotate when the piston 120 moves linearly. The second connecting member 160 is connected to the outside of the other end of the cylinder 110.

[0047] When the hydraulic and flywheel inertial damping combined vibration reduction device 100 is in use, the first connecting member 140 and the second connecting member 160 are respectively connected to two structures with relative vibration (such as the ground and the equipment to be damped) or two ends of a structure with relative vibration (such as two parts on a bridge), so that the hydraulic and flywheel inertial damping combined vibration reduction device 100 plays the role of energy dissipation and vibration reduction between the two. The first connecting member 140 drives the piston 120 to move linearly under the action of vibration, and the outer wall of the piston 120 and the inner wall of the first accommodating chamber A in the cylinder 110 are slidably matched and sealed, so that when the piston 120 moves linearly in the first accommodating chamber A, most of the viscous fluid (such as oil) flows from one sub-chamber of the first accommodating chamber A to another sub-chamber through the piston hole 120a and the spiral conduit 130. In the process of the flow of the viscous fluid, a reaction force is generated that is opposite to the direction of movement and is related to the movement speed and acceleration. This reaction force includes inertia force and damping force. The damping force is related to the speed, and the proportional factor is the viscous damping coefficient. The inertia force is related to the acceleration, and the proportional factor is the hydraulic inertia coefficient, thus generating viscous damping and hydraulic inertia. In addition, under the action of the transmission connection, the piston 120 can also drive the flywheel 150 to rotate when it moves linearly, generating flywheel inertia. The flywheel inertia is used to adjust and supplement the inertia coefficient, thereby improving the inertia effect of the vibration reduction device, thereby significantly improving the vibration reduction efficiency.

[0048] Optionally, a mechanism capable of converting linear motion into rotation is used to realize the transmission connection between the piston 120 and the flywheel 150. For example, a screw-nut mechanism, a gear rack mechanism, a worm gear mechanism, etc. can realize the transmission connection required by this embodiment.

[0049] In some embodiments, the hydraulic and flywheel inertial damping combined vibration reduction device 100 further includes a screw nut mechanism 170, and the piston 120 and the flywheel 150 are connected by means of the screw nut mechanism 170. Specifically, the screw nut mechanism 170 includes a screw 171 and a nut 172 that are spirally matched. When one of the screw 171 and the nut 172 is fixed in position in the axial direction x, the other of the screw 171 and the nut 172 can drive the former to rotate around the central axis when the former moves linearly along the axial direction x. Therefore, the piston 120 is connected to one of the screw 171 and the nut 172, and the flywheel 150 is connected to the other of the screw 171 and the nut 172, so that the piston 120 can drive the flywheel 150 to rotate when the latter moves linearly. In addition, in the screw-nut mechanism 170, the central axes of the screw 171 and the nut 172 coincide with each other. Compared with the rack and pinion mechanism and the worm gear mechanism in which the central axes of the two components are perpendicular to each other, the screw-nut mechanism 170 has a compact structure, which helps to reduce the size of the vibration reduction device and reduce costs.

[0050] Continue to refer to Figure 1As an optional embodiment, the screw nut mechanism 170 includes a screw 171 and a nut 172 that are screw-matched. The nut 172 is fixedly connected to the piston 120 to move linearly along the axial direction x with the piston 120. The screw 171 is fixed in position in the axial direction x, and one end of the screw 171 is connected to the flywheel 150 to drive the flywheel 150 to rotate under the drive of the nut 172. Figure 1 In the assembly method shown, the screw nut mechanism 170 is sealed in the first accommodating chamber A with viscous fluid. On the one hand, it prevents the screw nut mechanism 170 from contacting with the air and causing corrosion, which helps to increase the service life of the vibration reduction device. On the other hand, a small amount of viscous fluid will flow from one sub-chamber of the first accommodating chamber A to another sub-chamber through the gap between the nut 172 and the screw 171. The flow of this part of the viscous fluid can generate a nonlinear damping force with a low speed index, which can limit excessive damping output and effectively protect the vibration reduction device. In addition, in this assembly method, the position of the screw 171 is fixed, which helps to ensure the rigidity of the screw 171, thereby increasing the service life of the vibration reduction device.

[0051] Continue to refer to Figure 1 and Figure 2 In some embodiments, the piston 120 is provided with a second accommodating chamber B and two piston holes 120a. One of the piston holes 120a is connected to the second accommodating chamber B and one of the sub-chambers of the first accommodating chamber A, and the other piston hole 120a is connected to the second accommodating chamber B and another sub-chamber of the first accommodating chamber A. The spiral conduit 130 is arranged in the second accommodating chamber B, and the openings at both ends of the spiral conduit 130 are respectively connected to the two piston holes 120a. In this way, compared with the method of winding the spiral conduit 130 outside the cylinder 110, the structure arranged in this way is more compact and less prone to damage, and has a wider range of application scenarios.

[0052] Furthermore, the nut 172 includes a straight tube portion 1721 and a flange portion 1722. The straight tube portion 1721 is provided in the piston 120 and passes through the second accommodating chamber B. The flange portion 1722 abuts against one side of the piston 120 and is fixedly connected to the piston 120 by means of bolts. The spiral conduit 130 is wound around the outer side of the straight tube portion 1721. In this way, the connection strength between the nut 172 and the piston 120 is high and easy to assemble and disassemble. The straight tube portion 1721 of the nut 172 also plays a positioning role for the spiral conduit 130, avoiding the misalignment of the components of the vibration reduction device due to vibration during use, and improving the stability of the vibration reduction device.

[0053] In some embodiments, the hydraulic and flywheel inertial damping combined vibration reduction device 100 further includes a bearing 180, which is fixedly mounted on the cylinder 110 and connected to one end of the screw 171 connected to the flywheel 150, so as to support the screw 171 in the axial direction x. Specifically, the outer ring of the bearing 180 is fixedly embedded in the cylinder 110, and the inner ring of the bearing 180 is fixedly sleeved on one end of the screw 171 connected to the flywheel 150, so that the screw 171 has a rotational freedom around the central axis while being fixed in position in the axial direction x, and has high rotational precision, which helps to ensure the stability of the rotation of the flywheel 150.

[0054] In some embodiments, the hydraulic and flywheel inertia damping combined vibration reduction device 100 also includes a speed increaser 190. The input end 191 of the speed increaser 190 is connected to one end of the screw 171, and the output end 192 of the speed increaser 190 is connected to the flywheel 150. The flywheel inertia coefficient is related to the flywheel rotational inertia, the speed increaser ratio, and the screw lead. In this embodiment, the flywheel speed is increased by the speed increaser 190 to increase the flywheel inertia coefficient, further improving the inertia effect of the vibration reduction device and improving the vibration reduction efficiency. In addition, the connection between the screw 171 and the flywheel 150 is convenient for assembly and disassembly, and the ratio of the inertia coefficient to the damping coefficient can also be adjusted by replacing the flywheel 150 of different specifications, so as to adapt to the actual conditions of different application scenarios.

[0055] In some embodiments, the first connecting member 140 includes a push rod 142 and a movable ear plate 141. The push rod 142 is slidably arranged in the cylinder 110, and one end of the push rod 142 is fixedly connected to the piston 120. The movable ear plate 141 is arranged outside one end of the cylinder 110 and is fixedly connected to the other end of the push rod 142. The second connecting member 160 is a fixed ear plate fixedly arranged outside the other end of the cylinder 110. The hydraulic and flywheel inertial damping combined vibration reduction device 100 is connected to the target vibration reduction structure through the movable ear plate 141 and the fixed ear plate. The movable ear plate 141 drives the piston 120 and the nut 172 to make linear motion through the push rod 142, and then drives the screw 171 to drive the flywheel 150 to rotate.

[0056] Furthermore, a guide hole 110a is provided on the cylinder 110, and the central axis of the guide hole 110a is parallel to the axial direction x, and the push rod 142 is slidably penetrated through the cylinder 110 through the guide hole 110a. In this way, the guide hole 110a guides the push rod 142 along the axial direction x, so that the push rod 142 drives the piston 120 to move along the axial direction x, and on the basis of the sliding cooperation between the outer wall of the piston 120 and the inner wall of the first accommodating chamber A, the stability of the movement of the piston 120 in the first accommodating chamber A is further guaranteed.

[0057] As another optional embodiment, the screw nut mechanism 170 includes a screw 171 and a nut 172 that are spirally matched. The two ends of the screw 171 are respectively connected to the first connecting member 140 and the piston 120, and the first connecting member 140 drives the screw 171 and the piston 120 to perform linear motion along the axial direction x. The nut 172 is fixed in position in the axial direction x, and the outer side of the nut 172 is fixedly connected to the flywheel 150 to drive the flywheel 150 to rotate under the drive of the screw 171. Further, the first connecting member 140 is a movable ear plate 141 fixedly connected to one end of the screw 171, and the second connecting member 160 is a fixed ear plate fixedly arranged on the outer side of the other end of the cylinder 110.

[0058] Optionally, the screw nut mechanism 170 may adopt a ball screw nut mechanism. The ball screw nut mechanism is equipped with balls between the spiral grooves to convert sliding friction into rolling friction, and has the advantages of high transmission efficiency, high positioning accuracy, high rigidity, and long service life. On the one hand, it ensures that the flywheel 150 rotates smoothly to improve the vibration reduction efficiency of the vibration reduction device, and on the other hand, it increases the service life of the vibration reduction device.

[0059] In some embodiments, the cylinder 110 further has a third accommodating chamber C, and the flywheel 150 is disposed in the third accommodating chamber C. In this way, the cylinder 110 can also protect the flywheel 150, and prevent the flywheel 150 from colliding with other objects, thereby ensuring the rotation stability and service life of the flywheel 150. It can be understood that for the solution with the speed increaser 190, the speed increaser 190 can also be disposed in the third accommodating chamber C to protect the flywheel 150 and the speed increaser 190.

[0060] In summary, the hydraulic and flywheel inertia damping combined vibration reduction device 100 provided in the embodiment of the present invention comprises a cylinder 110, a piston 120, a spiral conduit 130, a first connecting member 140, a flywheel 150, a second connecting member 160, a screw nut mechanism 170, a bearing 180 and a speed increaser 190. The first connecting member 140 and the second connecting member 160 are respectively used to connect two structures with relative vibration or two ends of a structure with relative vibration. The first connecting member 140 drives the piston 120 to perform linear motion in the first accommodating chamber A of the cylinder 110, so that most of the viscous fluid flows from one sub-chamber to another sub-chamber through the piston hole 120a and the spiral conduit 130, generating viscous damping and hydraulic inertia, and a small amount of viscous fluid passes through the gap between the nut 172 and the screw 171. When the piston 120 performs linear motion, it also drives the flywheel 150 to rotate at a high speed through the connection of the speed increaser 190, generating flywheel inertia. The piston 120 and the flywheel 150 are connected by means of a screw nut mechanism 170 to reduce the size of the vibration reduction device and reduce the cost. The bearing 180 is used to support the screw 171 in the axial direction x to improve the rotation accuracy to ensure the stability of the rotation of the flywheel 150. The speed increase ratio of the speed increaser 190 is adjustable to increase the flywheel inertia. The hydraulic and flywheel inertia damping combined vibration reduction device 100 of the present invention can not only generate viscous damping and hydraulic inertia, but also generate flywheel inertia. The inertia coefficient is adjusted and supplemented by the flywheel inertia, and the inertia effect of the vibration reduction device is improved, thereby significantly improving the vibration reduction efficiency.
