Description

Technical Field

[0001] The present invention relates to the field of vibration reduction technology, and in particular to an inertial capacity vibration reduction device and method. Background Art

[0002] Engineering structures will produce horizontal or vertical vibrations under the action of earthquakes, wind loads, train loads, etc., especially horizontal vibrations, which can easily induce problems such as the safety or comfort of engineering structures. Therefore, it is particularly important to take more effective vibration reduction measures for engineering structures. A large number of scholars have conducted extensive research on this.

[0003] Dynamic vibration absorption technology based on the principle of energy dissipation and frequency modulation has been designed and applied in the field of vibration resistance. The basic idea is to attach a substructure to the structure, and by setting the substructure (shock absorber) to resonate with the same frequency as the structure, a large amount of structural vibration energy is transferred to the shock absorber, and then the energy is dissipated through the energy dissipation device inside the shock absorber, thereby achieving the effect of vibration reduction. The current shock absorber is mainly a tuned mass damper (TMD), which contains components such as mass, stiffness, and damping. The first two play a role in regulating the frequency, and the latter consumes energy. However, it has significant technical defects: its mass generally reaches about 5% of the mass of the main structure. Excessive mass and size will have an adverse effect on the bearing capacity of the structure and make the installation of TMD difficult.

[0004] Therefore, some scholars have proposed to use inertia elements to replace part of the physical mass. Through the conversion of translational and rotational energy, the "equivalent mass" that works is tens or even hundreds of times of its own physical mass. In this way, the physical mass of the device is reduced and the effect of mass efficiency is achieved. At present, the research on dynamic vibration absorption technology with additional inertia is in full swing, but the existing inertia vibration reduction devices still have technical shortcomings. First, the existing inertia vibration reduction devices are mostly linear structures with narrow adjustment bandwidth and insufficient robustness; second, due to the hysteresis of the displacement of the inertia vibration reduction device, after the external load stops, the reaction force of the inertia on the inertia vibration reduction device will not stop immediately, but will drive the structure to vibrate, resulting in adverse effects.

It should also be understood that the terms "include / comprise" or "have" etc. specify the presence of stated features, wholes, steps, operations, components, parts or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0026] Reference Figure 1~2 As shown, the present invention provides a technical solution: an inertia vibration reduction device, comprising a frame 10, a mass block 30, a plurality of elastic members 20, a transmission mechanism 40 and at least one pair of damping mechanisms 50, the frame 10 having a first side wall 11 and a second side wall 12 arranged perpendicular to each other, the mass block 30 is arranged in the frame 10 and opposite to the first side wall 11; the plurality of elastic members 20 abut between the first side wall 11 and the mass block 30; the transmission mechanism 40 is connected to a side of the mass block 30 away from the elastic member 20; at least one pair of damping mechanisms 50 is connected to the transmission mechanism 40, and the pair of damping mechanisms 50 are symmetrically arranged with the horizontal axis as the symmetry axis.

[0027] It should be noted that Figure 1 As a commonly used placement viewing angle, the horizontal axis is formed by connecting the center points of the first side wall 11 and the side wall opposite to the first side wall 11 .

[0028] In this embodiment, the force is transmitted to the transmission mechanism 40 through the mass block 30, and the transmission mechanism 40 converts the translational energy into rotational energy, and then consumes the rotational energy through the damping mechanism 50. Thus, a sufficient adjustment frequency band is ensured, and after the external load stops, the inertia capacity vibration reduction device can avoid the adverse effect of the hysteresis of the inertia capacity on the structure.

[0029] In addition, when the mass block 30 is subjected to external load, the elastic member can limit the maximum displacement of the mass block on the one hand, and can modulate the frequency on the other hand. That is, the displacement of the mass block 30 is due to the inertia of the mass block 30 when the controlled structure vibrates, and a displacement difference is generated between the mass block 30 and the controlled structure, thereby driving the inertia and the elastic member 20 to move.

[0030] Reference Figures 2~4 As shown, in some embodiments, the transmission mechanism 40 includes a first transmission assembly 41 and a second transmission assembly 42, the first transmission assembly 41 includes a first support shaft 411, a second support shaft 412, a connecting shaft 413, a transmission member 414, a first transmission gear plate 415, a second transmission gear plate 416 and a rack 417, the first support shaft 411 and the second support shaft 412 are arranged at intervals in a direction facing the mass block 30, one end of the first support shaft 411 and the second support shaft 412 are both connected to the second side wall 12, and the connecting shaft 413 is connected to the second side wall 12. 413 is connected to the first support shaft 411 and the second support shaft 412, the first transmission gear plate 415 and the second transmission gear plate 416 are arranged on the first support shaft 411 and the second support shaft 412 in a one-to-one manner, the second transmission gear plate 416 has a first boss, and the first boss is sleeved with a first gear 4161, the transmission member 414 is arranged on the connecting shaft 413, the rack 417 is meshed with the first gear 4161, one end of the rack 417 is connected to the mass block 30, and the second transmission assembly 42 is connected to the first transmission gear plate 415.

[0031] Exemplarily, the first support shaft 411 and the second support shaft 412 are fixed to the second side wall 12. The first transmission gear plate 415 and the first support shaft 411 are clearance fit or bearing connection, etc., and the second transmission gear plate 416 and the second support shaft 412 are clearance fit or bearing connection, etc. The transmission member 414 and the connecting shaft 413 are sleeve connection, etc. The transmission member 414, the first transmission gear plate 415 and the second transmission gear plate 416 are all prior art, and the specific structures and working principles of the three are not described in detail here.

[0032] In this embodiment, when the mass block 30 exerts a force on the rack 417, the rack 417 drives the first gear 4161 to rotate, so that the second transmission toothed disc 416 rotates accordingly. At the same time, the second transmission toothed disc 416 drives the first transmission toothed disc 415 to rotate through the transmission member 414, thereby converting the translational energy into rotational energy. When the energy is converted in this way, the first transmission assembly 41 and the second transmission assembly 42 can amplify the energy, so that the transmission mechanism 40 can improve the energy consumption efficiency.

[0033] Reference Figure 4As shown, in some embodiments, the transmission member 414 includes a first adjusting portion 4141 and a second adjusting portion 4142, the first adjusting portion 4141 is sleeved on the connecting shaft 413, the serrated end of the first adjusting portion 4141 is engaged with the second transmission gear plate 416, and the second adjusting portion 4142 is arranged on the first adjusting portion 4141, and the serrated end of the second adjusting portion 4142 is engaged with the first transmission gear plate 415.

[0034] Exemplarily, in order to ensure that the second adjustment portion 4142 remains stationary when adjusting the inertia coefficient, the second adjustment portion 4142 can be fixed to the second side wall 12 by a support sleeve, etc., and the first adjustment portion 4141 and the connecting shaft 413 can be keyed, transitionally fit, or interference fit, etc. The second adjustment portion 4142 and the first adjustment portion 4141 can be clearance fit, etc. The connecting shaft 413 and the first support shaft 411 and the second support shaft 412 can be clearance fit, etc.

[0035] In this embodiment, the first adjusting portion 4141 is driven to change its meshing position with the second transmission gear plate 416 by moving the connecting shaft 413, so that the radius ratio between the meshing position of the first adjusting portion 4141 with the second transmission gear plate 416 and the meshing position of the second adjusting portion 4142 with the first transmission gear plate 415 changes. When the energy is converted between the translational energy and the rotational energy, the energy conversion rate of the two changes, thereby changing the inertia coefficient.

[0036] The adjustment here can be regarded as a manual mode; for example, when the first transmission assembly 41 is assembled or in normal use.

[0037] Reference Figure 2 and 3 As shown, in some embodiments, the second transmission assembly 42 includes a first transmission part 421 and a second transmission part 422, the first transmission part 421 is sleeved on the first transmission gear plate 415, the number of the second transmission parts 422 is related to the number of the damping mechanisms 50, and at least two second transmission parts 422 are connected to the first transmission part 421 or are connected through a connecting part.

[0038] Exemplarily, the first transmission part 421 and the second transmission part 422 may both be gears or synchronous wheels, etc., and the connecting part may be a chain or a synchronous belt, etc. When the first transmission part 421 and the second transmission part 422 are both gears, the two may be meshed or connected by chain transmission; when the first transmission part 421 and the second transmission part 422 are both synchronous wheels, the two may be connected by synchronous belt transmission.

[0039] In this embodiment, the second transmission part 422 can transmit the rotational energy to the damping mechanism 50 so that the damping mechanism 50 consumes the energy.

[0040] Reference Figure 2~3As shown in and 5, in some embodiments, the transmission mechanism 40 includes a third transmission assembly 43, the third transmission assembly 43 includes a third support shaft 431, a rotating wheel 432, a fourth support shaft 433 and a connecting rod 434, one end of the third support shaft 431 is fixed to the second side wall 12, the rotating wheel 432 is rotatably disposed on the third support shaft 431, the rotating wheel 432 has a second boss, and the second boss is sleeved with a second gear meshing with the rack 417, the fourth support shaft 433 is disposed on the side of the rotating wheel 432 away from the second side wall 12, and the connecting rod 434 is connected one-to-one to one end of the connecting shaft 413 close to the second transmission gear disc 416 and the fourth support shaft 433.

[0041] Exemplarily, the rotating wheel 432 may be a circular wheel or a cam, etc.

[0042] In this embodiment, when the rack 417 moves, it drives the second gear to rotate, so that the rotating wheel 432 rotates accordingly. The connecting shaft 413 is driven to move in the horizontal direction by the connecting rod 434, so that the first adjusting part 4141 moves in the horizontal direction accordingly, thereby achieving a change in the radius ratio between the meshing position of the first adjusting part 4141 in the second transmission toothed disc 416 and the meshing position of the second adjusting part 4142 in the first transmission toothed disc 415. In this way, the first transmission assembly 41 and the second transmission assembly 42 can be linked to each other, so that the energy conversion rate between the translational energy and the rotational energy can be further improved.

[0043] Reference Figure 2~3 As shown in Figures 6 to 7, in some embodiments, the damping mechanism 50 includes a fifth support shaft 51, a ratchet pawl assembly 52 and a damping member 53, the fifth support shaft 51 is rotatably disposed on the second side wall 12, the ratchet of the ratchet pawl assembly 52 is sleeved on the fifth support shaft 51, the ratchet of the ratchet pawl assembly 52 has a third boss and a damping chamber 521, the second transmission portion 422 is sleeved on the third boss, the damping member 53 is disposed in the damping chamber 521, one end of the damping member 53 is connected to the fifth support shaft 51, and the other end of the damping member 53 is connected to the inner wall of the damping chamber 521.

[0044] Exemplarily, the damping member 53 may be a coil spring or a tension spring, etc. When the damping member 53 is a tension spring, the number of the tension springs is preferably two or more, and they are arranged according to the rotation direction of the ratchet wheel of the ratchet pawl assembly 52. ​​The pawl of the ratchet pawl assembly 52 is connected to the second side wall 12 through a support rod, etc., and a torsion spring is arranged between the pawl of the ratchet pawl assembly 52 and the support rod, so that the pawl of the ratchet pawl assembly 52 is kept in close contact with the saw teeth of the ratchet wheel of the ratchet pawl assembly 52.

[0045] In this embodiment, when the second transmission part 422 rotates, the fifth support shaft 51 is driven to rotate, so that the ratchet of the ratchet pawl assembly 52 rotates accordingly. The damping member 53 generates a large damping effect due to the rotation of the fifth support shaft 51, thereby performing an energy effect.

[0046] It should be noted that, refer to Figure 8 As shown, during assembly, there is a rotation angle difference between the ratchets of a pair of ratchet pawl assemblies 52, that is, in one ratchet pawl assembly 52, the pawl is not inserted into the tooth groove of the ratchet wheel; in the other ratchet pawl assembly 52, the pawl is inserted into the tooth groove of the ratchet wheel. Such an arrangement can ensure that during a whole reciprocating stroke, one ratchet pawl assembly 52 consumes energy while the other ratchet pawl assembly 52 brakes.

[0047] For example, based on Figure 8 From the perspective of , it is assumed that the ratchet of the ratchet and pawl assembly 52 on the left is named ratchet A, the ratchet of the ratchet and pawl assembly 52 on the right is named ratchet B, the ratchet of the ratchet and pawl assembly 52 on the left is named ratchet A, and the ratchet of the ratchet and pawl assembly 52 on the right is named ratchet B. In the stroke of the mass block 30 moving toward the first side wall 11, the ratchet B rotates clockwise, the pawl B slides along the back of the teeth of the ratchet B, the pawl B rotates outward, and gradually enters the next tooth groove of the ratchet B; at this time, the damping member 53 of the ratchet B consumes energy. While the ratchet A rotates counterclockwise, the pawl A slides along the back of the teeth of the ratchet A, the pawl B rotates inward, and gradually enters the current tooth groove of the ratchet B; at this time, the pawl B cooperates with the current tooth groove of the ratchet B to brake. In the stroke of the mass block 30 moving away from the first side wall 11, the movement directions of the ratchet A, the ratchet B, the pawl A and the pawl B are opposite to the above.

[0048] In some embodiments, the damping chamber 521 is provided with damping fluid. The damping member 53 is preferably a coil spring.

[0049] In this embodiment, when the damping member 53 is deformed, the energy consumption efficiency can be further improved through the friction effect of the damping fluid on the damping member 53.

[0050] Reference Figure 3 and 7 As shown, in some embodiments, a liquid inlet nozzle 522 communicating with the damping chamber 521 is provided on the ratchet of the ratchet pawl assembly 52 .

[0051] In this embodiment, the liquid inlet nozzle 522 is useful for adding or replacing the damping liquid.

[0052] Terminology explanation: Translational energy: the energy input to the transmission mechanism 40 when the mass block 30 moves in the horizontal direction.

[0053] Rotational energy: kinetic energy when the first transmission gear plate 415, the second transmission gear plate 416 and the rotating wheel 432 rotate.
