Description

TECHNICAL FIELD

[0001] The present application relates to the field of vibration reduction technology, in particular to a kind of inertial mass damper device and method. BACKGROUND

[0002] Engineering structure will produce horizontal or vertical vibration under the action of earthquake, wind load, train load, etc., especially horizontal vibration is easy to induce engineering structure safety or comfort problem, therefore it is particularly important to take more effective vibration reduction measures to engineering structure, a large number of scholars have carried out extensive research on this.

[0003] Based on the principle of energy dissipation and frequency modulation, dynamic vibration absorber technology is designed and applied in the field of anti-vibration, its basic idea is to attach a substructure to the structure, and the substructure (damper) is set to resonate with the structure frequency to transfer a large amount of structure vibration energy to the damper, and then dissipate the energy through the energy dissipation device inside the damper to achieve the effect of vibration reduction. The current damper is mainly tuned mass damper (TMD), which contains mass, stiffness and damping elements, among which the first two elements play a role in adjusting the frequency, and the latter consumes energy. But it has a significant technical defect: its mass generally reaches about 5% of the mass of the main structure, and the large mass and size will adversely affect the carrying capacity of the structure and make it difficult to install TMD.

[0004] Therefore, scholars have proposed to use inertial mass elements to replace part of the physical mass, which can convert translational and rotational energy to make the "equivalent mass" several tens or even hundreds of times its physical mass, thus achieving the reduction of physical mass of the device and achieving the effect of mass efficiency. The research on dynamic vibration absorber technology with additional inertial mass is in full swing, but the existing inertial mass damper device still has technical shortcomings.

It should also be understood that the term "comprising" or "having" etc., as used herein, specifies the presence of stated features, integers, steps, operations, components, parts, or combinations thereof, but does not preclude the presence or addition of one or more other features, integers, steps, operations, components, parts, or combinations thereof.

[0048] Reference Figures 1-2As shown, the present application provides a technical solution: a kind of inertial damper device, including frame 10, mass 30, multiple elastic members 20, transmission mechanism 40 and at least a pair of damping mechanism 50, frame 10 has the first side wall 11 and the second side wall 12 of mutual vertical arrangement, mass 30 is located in frame 10 and is oppositely arranged with the first side wall 11;Multiple elastic members 20 are abutted between the first side wall 11 and mass 30;Transmission mechanism 40 is connected to the side of mass 30 away from elastic member 20;At least a pair of damping mechanism 50 is connected to transmission mechanism 40, and a pair of damping mechanism 50 is symmetrically arranged with horizontal axis as symmetry axis.

[0049] Need to be explained, Figure 1 As the commonly used display angle of view, 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.

[0050] In this embodiment, the force is transmitted to the transmission mechanism 40 by the mass 30, the translational energy is converted into rotational energy by the transmission mechanism 40, and the rotational energy is consumed by the damping mechanism 50. Thus, sufficient adjustment frequency band is ensured, and after the external load stops, the inertial damper device can avoid the adverse effects of the inertia of the inertial damper on the structure.

[0051] In addition, when the mass 30 is subjected to external load, the elastic member can limit the maximum displacement of the mass 30 on the one hand, and can adjust the frequency on the other hand. That is, when the mass 30 is subjected to external load, the mass 30 has inertia due to the vibration of the controlled structure, and displacement difference is generated between the mass 30 and the controlled structure, thereby driving the inertial damper and the elastic member 20 to move.

[0052] Referring to 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 disc 415, a second transmission gear disc 416 and a rack 417, the first support shaft 411 and the second support shaft 412 are arranged in a direction facing the mass 30, one end of the first support shaft 411 and the second support shaft 412 is connected to the second side wall 12, the connecting shaft 413 is connected to the first support shaft 411 and the second support shaft 412, the first transmission gear disc 415 and the second transmission gear disc 416 are correspondingly arranged on the first support shaft 411 and the second support shaft 412, the second transmission gear disc 416 has a first boss, a first gear 4161 is sleeved on the first boss, the transmission member 414 is arranged on the connecting shaft 413, the rack 417 is engaged with the first gear 4161, one end of the rack 417 is connected to the mass 30, and the second transmission assembly 42 is connected to the first transmission gear disc 415.

[0053] The first support shaft 411 and the second support shaft 412 are fixed to the second side wall 12. The first transmission disc 415 is in clearance fit or bearing connection with the first support shaft 411, and the second transmission disc 416 is in clearance fit or bearing connection with the second support shaft 412. The transmission member 414 is in sleeve connection with the connecting shaft 413. The transmission member 414, the first transmission disc 415 and the second transmission disc 416 are all prior art, and the specific structure and working principle thereof will not be described in detail herein.

[0054] In this embodiment, when the mass 30 exerts a force on the rack 417, the rack 417 drives the first gear 4161 to rotate, and the second transmission disc 416 rotates accordingly. At the same time, the second transmission disc 416 drives the first transmission disc 415 to rotate through the transmission member 414, thereby converting the translational energy into rotational energy. In this energy conversion, 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.

[0055] Referring to Figure 4 In some embodiments, the transmission member 414 includes a first adjusting part 4141 and a second adjusting part 4142. The first adjusting part 4141 is sleeved on the connecting shaft 413, and the sawtooth end of the first adjusting part 4141 is engaged with the second transmission disc 416. The second adjusting part 4142 is arranged on the first adjusting part 4141, and the sawtooth end of the second adjusting part 4142 is engaged with the first transmission disc 415.

[0056] In order to ensure that the second adjusting part 4142 remains stationary when adjusting the inertance coefficient, the second adjusting part 4142 can be fixed to the second side wall 12 through a support sleeve, and the first adjusting part 4141 and the connecting shaft 413 can be in key connection, transition fit or interference fit, etc. The second adjusting part 4142 and the first adjusting part 4141 can be in clearance fit, etc. The connecting shaft 413 and the first support shaft 411 and the second support shaft 412 can be in clearance fit, etc.

[0057] In this embodiment, by moving the connecting shaft 413 to drive the first adjusting part 4141 to change the engagement position with the second transmission disc 416, the radius ratio of the engagement position of the first adjusting part 4141 with the second transmission disc 416 and the engagement position of the second adjusting part 4142 with the first transmission disc 415 changes. When the translational energy and the rotational energy are converted, the energy conversion rates of the two change, thereby changing the inertance coefficient.

[0058] Here, the adjustment can be regarded as a manual mode; for example, when the first transmission assembly 41 is assembled or used regularly.

[0059] Referring to Figure 2 and 3As shown, in some embodiments, the second transmission assembly 42 comprises a first transmission part 421 sleeved on the first transmission gear disc 415 and a second transmission part 422, the number of the second transmission part 422 is associated with the number of the damping mechanism 50, and at least two second transmission parts 422 are connected with the first transmission part 421 or connected through a connecting part.

[0060] For example, the first transmission part 421 and the second transmission part 422 can be gears or synchronous wheels, and the connecting part can be a chain or a synchronous belt. When the first transmission part 421 and the second transmission part 422 are gears, they can be meshed or connected through a chain; when the first transmission part 421 and the second transmission part 422 are synchronous wheels, they can be connected through a synchronous belt.

[0061] In this embodiment, the second transmission part 422 can transmit rotational energy to the damping mechanism 50 to make the damping mechanism 50 consume energy.

[0062] Referring to Figures 2-3 As shown in FIGS. 4 and 5, in some embodiments, the transmission mechanism 40 comprises a third transmission assembly 43, the third transmission assembly 43 comprises 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 arranged on the third support shaft 431, the rotating wheel 432 has a second boss, a second gear 4321 engaged with the rack 417 is sleeved on the second boss, the fourth support shaft 433 is arranged on a side of the rotating wheel 432 away from the second side wall 12, and the connecting rod 434 is connected to one end of the connecting shaft 413 close to the second transmission gear disc 416 and the fourth support shaft 433 in one-to-one correspondence.

[0063] For example, the rotating wheel 432 can be a round wheel or a cam.

[0064] In this embodiment, when the rack 417 moves to drive the second gear 4321 to rotate, the rotating wheel 432 follows to rotate. Through the connecting rod 434, the connecting shaft 413 is driven to move in the horizontal direction, so that the first adjusting part 4141 follows to move in the horizontal direction, thereby realizing the change of the radius ratio of the engagement position of the first adjusting part 4141 on the second transmission gear disc 416 and the engagement position of the second adjusting part 4142 on the first transmission gear disc 415. In this way, the first transmission assembly 41 and the second transmission assembly 42 can be linked, so as to further improve the energy conversion rate between the translational energy and the rotational energy.

[0065] Referring to Figures 2-3As shown in Figures 6 and 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 part 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.

[0066] For example, the damping member 53 may be a coil spring or a tension spring. When the damping member 53 is a tension spring, the number of 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 via a support rod, etc. A torsion spring is provided between the pawl of the ratchet pawl assembly 52 and the support rod to ensure that the pawl of the ratchet pawl assembly 52 maintains close contact with the teeth of the ratchet wheel of the ratchet pawl assembly 52.

[0067] In this embodiment, when the second transmission part 422 rotates, it drives the fifth support shaft 51 to rotate, causing the ratchet of the ratchet pawl assembly 52 to rotate accordingly. The damping member 53 generates a large damping effect due to the rotation of the fifth support shaft 51, thereby achieving an energy effect.

[0068] It should be noted that, referring to Figure 8 As shown, during assembly, the ratchets of the pair of ratchet pawl assemblies 52 have a rotational angle difference, i.e., in one ratchet pawl assembly 52, the pawl is not inserted into the ratchet tooth groove; in the other ratchet pawl assembly 52, the pawl is inserted into the ratchet tooth groove. This arrangement ensures that during the entire reciprocating stroke, one ratchet pawl assembly 52 is consuming energy while the other ratchet pawl assembly 52 is braking.

[0069] For example, based on Figure 8 From this perspective, let's assume that the ratchet of the left ratchet and pawl assembly 52 is named ratchet A, the ratchet of the right ratchet and pawl assembly 52 is named ratchet B, the pawl of the left ratchet and pawl assembly 52 is named pawl A, and the pawl of the right ratchet and pawl assembly 52 is named pawl B. During the movement of the mass block 30 toward the first side wall 11, ratchet B rotates clockwise, pawl B slides along the back of the teeth of ratchet B, and pawl B rotates outward, gradually entering the next tooth groove of ratchet B. At this time, the damping element 53 of ratchet B consumes energy. Ratchet A rotates counterclockwise, pawl A slides along the back of the teeth of ratchet A, and pawl B rotates inward, gradually entering the current tooth groove of ratchet B. At this time, pawl B cooperates with the current tooth groove of ratchet B to brake. During the movement of the mass block 30 away from the first side wall 11, the movement directions of ratchet A, ratchet B, pawl A, and pawl B are opposite to those described above.

[0070] In some embodiments, the damping chamber 521 is provided with a damping fluid. The damping member 53 is preferably a coil spring.

[0071] 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.

[0072] 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 .

[0073] In this embodiment, the liquid inlet nozzle 522 is useful for adding or replacing the damping liquid.

[0074] Explanation of terms:

[0075] Translational energy: the energy input to the transmission mechanism 40 when the mass block 30 moves in the horizontal direction.

[0076] Rotational energy: kinetic energy generated when the first transmission gear plate 415 , the second transmission gear plate 416 and the rotating wheel 432 rotate.

[0077] The present invention provides a technical solution: a method for inertia volume vibration reduction, applicable to the above-mentioned inertia volume vibration reduction device, comprising the following steps:

[0078] S1, the mass 30 is subjected to external vibration force and moves horizontally, generating translational energy on the transmission mechanism 40;

[0079] S2, converting the translational energy into rotational energy through the transmission mechanism 40 and transmitting it to at least one pair of damping mechanisms 50;

[0080] S3, consuming the rotational energy through at least one pair of damping mechanisms 50.

[0081] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
