Description

Technical Field

[0001] The present invention belongs to the technical field of structural vibration control, and particularly relates to a cross-layer tuned mass damping inerter device applicable to a wind turbine tower. Background Art

[0002] In the application process of civil engineering buildings and offshore platform structures, based on the principle of dynamics, various facilities will inevitably have dynamic responses under the influence of the external environment. Such vibration responses are acceptable within a certain range. If the vibration response is too large, it is necessary to consider absorbing the vibration of the overall structure. Common vibration absorbers include tuned mass dampers (TMD) and tuned liquid column dampers (TLCD), and these vibration absorbers have been applied to vibration response protection.

[0003] Based on the design of traditional vibration absorbers and combined with actual application requirements, a tuned mass damping inerter (TMDI) has been designed. The tuned mass damping inerter (TMDI) is a device that combines a traditional tuned mass damper (TMD) with an inertial device, and it plays an important role in structural vibration control and energy harvesting through its unique mechanical properties. When the main structure of the system is excited by an external load and generates a vibration response, the TMDI structure will generate an inertial force acting on the main structure in the direction opposite to the vibration direction of the structure. This inertial force helps to attenuate the vibration response of the main structure, thereby achieving effective control of the vibration response. And during the attenuation process, the inertial device can collect, recycle, and reuse energy through rotational motion. Thus, it can be seen that TMDI has broad prospects in the field of vibration control of large buildings.

[0004] On the basis of the TMDI design, in order to better meet the demand for insufficient space utilization of the system structure, further improvement is needed. The introduced cross-layer tuned mass damping inerter design is a vibration control system that combines a tuned mass damper, an inerter element, and a cross-layer mechanism on the basis of a framework. In the cross-layer design, the tuned mass damper at the top is tightly connected to the inerter element structure between different levels through a pulley cable. After the overall structure has a vibration response, the top damper drives the cross-layer inerter element to move, generating an inertial force acting in the direction opposite to the vibration direction of the main structure, and the overall can achieve better vibration reduction effect. Summary of the Invention

[0010] In a preferred embodiment of the present invention, a spring fixing screw hole (14) is arranged on the side surface of the slider base (1)(11) for connecting the steel wire; two fixed connection ends (13) are arranged on both sides of the surface of the slider base (11) for connecting with the cross-layer mechanism.

[0011] In a preferred embodiment of the present invention, the inerter element includes a ball screw assembly, a second base plate (15), a second mounting bracket (17), a third mounting bracket (18), and a second track (16). The second base plate (15) is fixed on the third-layer base plate of the overall frame.

The ball bearing (21) is in the shape of a stepped cylinder, and a closed ball slide rail is designed inside it, containing balls.

[0016] Compared with the prior art, the embodiment of the present invention provides a cross-layer tuned mass damping inerter device applicable to a wind turbine tower, which has the following beneficial effects:

[0017] (1) For the problem that the inerter element cannot fully play its role, the present invention arranges and connects the inerter element and the top-layer tuned mass damper across layers. Compared with installing the inerter on the top layer, it can better play the effect and enhance the vibration reduction performance. For the problem of weak vibration reduction performance, the present invention introduces an inerter element into the traditional tuned mass damper (TMD), realizes the conversion of energy forms through the acceleration difference at both ends of the inerter, and enhances the vibration reduction performance through optimized structural design. For the problem of low space utilization rate, the present invention conducts a cross-layer design on the basis of the tuned mass damping inerter (TMDI), and realizes a high-utilization layered layout without reducing the performance by arranging the tuned mass damper and the inerter element across layers. For the characteristic of poor robustness, the present invention finds the optimal damper system design through experiments and simulations, so that the entire system can achieve a strong vibration control effect under different vibration conditions.

[0018] (2) The present invention proposes a structural design scheme for a cross-layer tuned mass damping inerter, and further innovatively designs the specific structure on the basis of the tuned mass damping inerter (TMDI), converting from a single-layer control mode to a cross-layer control mode, improving the space utilization rate and the shock absorption effect, and there is a high-order damping effect during the vibration process, which can control the high-order mode.

[0019] (3) In the present invention, the tuned mass damper structure is placed at the top layer of the overall frame. The tuned mass damper structure is connected to the cross-layer inertial element through a cable with negligible elasticity. The position of the cable is fixed by the fourth mounting bracket and the fixed pulley to ensure symmetry in the spatial structure. A flywheel and a ball nut are applied in the inertial element to convert translational energy into rotational energy, enhancing the vibration absorption effect. It can be freely arranged across layers in space, overcoming the difficulties in the design of traditional dampers. In addition, the cross-layer arrangement can give full play to the functions of mass amplification and damping enhancement of the inertial element, and can improve the shock absorption effect with the same equipment configuration. At the same control frequency, compared with the TMD, the application of the cross-layer tuned mass damping inertial container design can not only significantly reduce the physical mass, but also increase the vibration absorption effect by about 15% and the space utilization rate by more than 30%. The present invention provides a structural design scheme for a cross-layer tuned mass damping inertial container, providing a strong reference for practical applications.

[0025] An embodiment of the present invention provides a cross - layer tuned mass damping inerter device applicable to a wind turbine tower, which includes an overall frame, a tuned mass damper, an inerter element, and a cross - layer mechanism; the overall frame includes a multi - layer structure, the tuned mass damper is installed on the top layer of the overall frame; the inerter element is installed on any layer except the tuned mass damper on the top layer; the cross - layer mechanism is used to connect the tuned mass damping inerter on the top layer and the inerter element on any layer.

[0026] As Figure 1 shown, the overall frame includes 2 connecting pieces 1, 4 counterweight aluminum blocks 2, spring steel plates 3, and multiple fastening screws 4. The overall frame is divided into four layers. The bottom plate of the fourth layer of the overall frame is composed of multiple interconnected spring steel plates 3. The spring steel plates 3 at the edge are fixed to the intersection of the side support plates 5 of the overall frame through connecting pieces 1 and fastening screws 4. The 4 counterweight aluminum blocks 4 are placed on the spring steel plates 3 and fixed to the overall frame through fastening screws 4. The overall frame in this embodiment is a dynamic equivalent model of an actual multi - layer structure, which represents but is not limited to multi - story building structures such as buildings and towers.

[0027] As Figure 2 shown, the tuned mass damper includes a first bottom plate 8, 2 first mounting brackets 9, a first track 10, a slider base 11, a mass block 12, and a rigid spring. The rigid spring is a steel plate with a bending stiffness similar to that of an actual multi - story building. The first bottom plate 8 is fixed to the spring steel plate 3, the first track 10 is fixed to the first bottom plate 8, the 2 first mounting brackets 9 are installed at the left and right ends of the first bottom plate 8, the slider base 11 is slidably installed on the first track 10, and the mass block 12 is arranged on the slider base 11. The mass block 12 is stacked by several mass sheets, and the mass sheets are fixed to each other by fastening screws so as not to move relatively, and at the same time, the fastening screws are fixed to the slider base 11. The slider base 11 can slide relative to the first track 5 to enable the mass block 8 to move relatively on the track 5, and the upper surface of the first track 10 is smooth. The rigid spring includes several springs, and both ends of the springs are connected to the slider base 11 and the 2 first mounting brackets 9 through steel wires respectively, and the springs are arranged in parallel. A spring fixing screw hole 14 is arranged on the side surface of the slider base 11 for connecting the steel wire; two fixed connection ends 13 are arranged on both sides of the surface of the slider base 11 for connecting with the cross - layer mechanism.

[0028] As Figure 3As shown in the figure, the inerter element includes a ball screw assembly, a second base plate 15, a second mounting bracket 17, a third mounting bracket 18, and a second track 16. The second base plate 15 is fixed on the third-layer base plate of the overall frame. The second track 16 is fixed on the second base plate 15, and the upper surface of the second track 16 is smooth. The second mounting bracket 17 is slidably fixed on the second track 16, and the third mounting bracket 18 is fixed on the second base plate 15; a ball screw assembly is connected to the tops of the second mounting bracket 17 and the third mounting bracket 18.

[0029] The ball screw assembly includes a screw rod 19, a flywheel 20, a ball bearing 21, and a ball nut 22; the screw rod 19 is movably connected to the tops of the second mounting bracket 17 and the third mounting bracket 18. Ball bearings 21 and ball nuts 22 are respectively installed on both sides of the top of the third mounting bracket 18 corresponding to the screw rod 19. The ball bearing 21 is in the shape of a stepped cylinder, and a closed ball slide rail is designed inside it, containing balls; when the screw rod 19 rotates, the balls will continuously circulate and roll on its thread groove and the track inside the bearing, thereby causing the ball bearing 21 to rotate accordingly. The flywheel 20 is fixed on the ball bearing 21, and there is no relative rotation between the two. This ball screw assembly can be installed on any layer except the top layer as needed to achieve the acceleration difference at both ends of the inerter, and is suitable for different application scenarios and application objects.

[0030] Figure 1 Combined with Figure 2 and Figure 3 , the cross-layer mechanism includes two cables, 4 fixed pulleys 7, and 4 fourth mounting brackets 6. Four fourth mounting brackets 6 are symmetrically arranged on the support plates 5 on both sides of the overall frame. Each fourth mounting bracket 6 fixes one fixed pulley 7. One end of the cable is connected to the mass block 12 and the slider base 11 on the tuned mass damper on the top layer, and is connected to the round holes at both ends of the screw rod 19 in the inerter element on the third layer through the fixed pulley 7 and the fourth mounting bracket 6. After the cable is fixed, it is tightened. By adjusting the distance between the fourth mounting bracket 6, the 4 fixed pulleys 7 and the support plates 5 on both sides of the overall frame, the pre-tension of the cable can be accurately adjusted. When the tuned mass damper on the top layer moves, it drives the inerter element structure to move relatively across layers, and under the connection of the cable, the tuned mass damper on the top layer is symmetric in position in the left-right direction.

[0031] The pre-tension of the cable of the cross-layer mechanism can be flexibly adjusted. By replacing the fourth mounting bracket 6, the distance between the 4 fixed pulleys 7 and the support plates 5 on both sides of the overall frame can be flexibly adjusted, thereby accurately adjusting the pre-tension of the cable, which provides convenience for studying the vibration control performance of the cross-layer tuned mass damper inerter under different pre-tensions.

[0032] As described above, the inertia of the inerter element is directly proportional to the acceleration difference between its two endpoints. That is, when the acceleration difference between the two endpoints increases, its mass amplification effect and damping enhancement effect will become more significant. Therefore, in practical applications, the acceleration difference between the two endpoints should be increased as much as possible to give full play to the performance advantages of the inerter element. The main purpose of the cross-layer layout is to give full play to the role of the inerter element. In the tuned mass damper structure on the top floor, the mass block 12 is stacked and installed on the slider base 11, and the number of mass blocks can be adjusted to change the mass of the damper part. Rigid springs are connected to both sides of the slider base 11 respectively. When the slider base 11 deviates from the equilibrium position, the rigid springs provide corresponding elastic forces for the mass block 12.

[0033] Two fixed connection ends 13 are arranged along the direction of the first slide rail 10 on the slider base 11. The connection ends are connected to the lead screw 19 in the ball screw assembly of different levels through the cable of the cross-layer mechanism. The overall position of the design is fixed by the fixed pulley 7 in the connection path to achieve symmetry in space. As Figure 1 shown, in different levels, taking the third level as an example, the lead screw moves horizontally together with the slider base and the ball bearing positions under the connection of the cable, so that the lead screw is guaranteed to be parallel to the slide rail. A ball nut is installed in the lead screw. When there is an acceleration difference between the ball nut, the lead screw and the slider base, the ball nut will rotate and drive the corresponding fixed flywheel to rotate together. During this process, the translational motion energy at both ends of the lead screw is converted into the rotational energy corresponding to the ball nut and the flywheel, so as to achieve inertia amplification and obtain an equivalent inertia mass exceeding the physical inertia. When the controlled main structure vibrates, the vibration of the base will cause the mass block to slide relatively in the track, thus driving the movement of the overall cross-layer tuned mass damper design structure. When the overall sliding period of the cross-layer structure is close to the control period of the controlled main structure, resonance will occur with the main structure, so as to achieve the purpose of tuned vibration control. In the whole cross-layer layout, for a multi-story frame structure, in its first-order vibration mode, the displacement and acceleration at the top are more significant than those of other floors. In order to further enhance the acceleration difference, the two endpoints of the ball screw assembly can be fixed on different floors through the cable, so as to achieve the amplification effect of the acceleration difference, so that the inerter element can play its role more efficiently.

[0034] In the design of the tuned mass damper for the entire top floor, the slider base is connected to the inerter element on the third floor (but not limited to the third floor) through cables at the fixed connection end. Each cable is fixed through three fixed pulleys in the connection path. By adjusting the positions of the fixed pulleys, the cable can be tightened. And by adjusting the distances between the mounting brackets, the fixed pulleys and the support plates on both sides of the overall frame, the pre-tension of the cable can be adjusted. The tuned mass inerter across floors under different pre-tensions can be studied. At the same time, through the first mounting bracket, the cable can be adjusted to be parallel to the first slide rail. That is, when the main structure vibrates and causes the damper to vibrate, the motion states of the tuned mass damper structure on the top floor and the inerter element structure can be coordinated. The main function of the rigid spring is to store and release energy. When the spring is subjected to an external force, it will undergo elastic deformation and store energy; when the external force disappears, the spring will return to its original state and release the stored energy. In this cross-floor layout, the main function of the rigid spring is to provide the necessary stiffness, so as to jointly form a spring-mass-damper system with the damper. This system has a specific natural frequency. By adjusting the stiffness of the spring and the mass of the mass block, the natural frequency of the system can be matched with the control frequency required by the main structure, thereby achieving the effect of tuned vibration absorption.

[0035] Place the inerter element at the centrally symmetric position on any floor. Connect the left and right ends of the lead screw to the tuned mass damper structure on the top floor through cables with negligible elasticity. When the main structure vibrates, the tuned mass damper on the top floor vibrates, and drives the overall movement of the inerter element across floors through the cable. The flywheel and the ball nut are tightly connected as a whole. During the movement of the lead screw, it rotates, and the ball nut also rotates. Therefore, during this process, the translational motion of the lead screw is converted into the rotational motion of the ball nut and the flywheel, realizing energy conversion. The overall movement structure is tightly fixed on the slide rail through the mounting bracket, and the surface of the slide rail is smooth. Through the above mechanism, the operation of the entire damper can be realized. Without changing the mass of the damper, through the cross-floor layout in the present invention, the improvement of the overall space utilization rate and the enhancement of the control ability can be achieved. The inerter element structure is connected to the tuned mass damper structure on the top floor through a cable, Figure 3 in which the lead screw is connected to Figure 2 the fixed connection section in, and both ends have the same acceleration and displacement of motion, which can achieve better effects compared to installing the inerter element on the top floor as well.

[0036] Although the present invention has been disclosed above with preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those of ordinary skill in the art can make various modifications and changes without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
