Problems solved by technology

However, the elastic elements in existing tuned mass damper products mainly rely on helical steel springs, and the variety of elastic elements is relatively single; The vibration damping performance of the product; moreover, the existing tuned mass damper is mostly attached to the building structure, which is greatly affected by the processing error and design change of the building structure, and sometimes affects the beauty of the building structure; fourth, it is affected by Due to the limitations of the existing product structure and the characteristics of elastic components, the natural frequency of the product is low, which is not suitable for controlling high-frequency vibration above 15Hz, and the scope of application is limited

Embodiment 1

[0049] like figure 1 and figure 2 The tuned mass damper with a frame of the present invention shown in the present invention includes an elastic element 4 and a mass block 3, and also includes a coupling frame 2, which contains a vibration-absorbing cavity 100, and the mass block 3 is arranged on the vibration-absorbing cavity of the coupling frame 2. In the cavity 100 , an elastic element 4 is provided between the mass block 3 and the cavity wall of the vibration-absorbing cavity 100 . Specifically, the elastic element 4 is arranged between the upper and lower surfaces of the mass block 3 and the wall of the vibration-absorbing cavity 100, the coupling frame 2 is made of aluminum alloy material, and the elastic element 4 is made of rubber material, because the rubber material has good damping properties , is a commonly used elastic solid damping material, so the elastic element 4 is also a damping element at the same time, and the mass block 3 is an iron block, wherein the ...

Embodiment 2

[0062] like Figure 4 The difference between the tuned mass damper with a frame of the present invention and the first embodiment is that the elastic element 4 is arranged between the left and right sides of the mass block 3 and the wall surface of the vibration-absorbing cavity 100, and the connecting frame 2 is made of glass fiber reinforced plastic. , the elastic element 4 is made of high-damping elastic polyurethane material, and the mass block 3 is made of steel material, wherein the elastic element 4 is fixedly connected with the mass block 3 and the wall of the vibration-absorbing cavity 100 through a chemical bonding process. In order to increase the reliability of the connection between the elastic element, the coupling frame and the mass block, a connection strengthening structure is respectively provided on the mating surface of the coupling frame and the elastic element and the mating surface of the mass block and the elastic element. The connection strengthening st...

Embodiment 3

[0066] like Figure 5The difference between the tuned mass damper with a frame of the present invention and the first embodiment is that the coupling frame 2 is made of steel, and the elastic element 4 adopts a metal spring, which is specifically a spiral steel spring in this example. The two ends are respectively welded and fixed on the connection frame 2 and the mass block 3 . In addition, in order to ensure that the elastic element 4 always forms an effective support for the mass block 3 during use, the elastic element 4 is pre-compressed when it is assembled with the mass block 3 and the coupling frame 2, and is in a pre-compressed state, and the elastic element 4 The pre-compression displacement is greater than the vibration amplitude of the mass block 3 relative to the wall of the vibration-absorbing cavity 100 when it is working.

[0067] The technical solution described in this example is the same as the application method in Example 1, and will not be repeated here. ...

Abstract

The invention belongs to a tuned mass damper with a frame. The tuned mass damper with the frame is characterized by comprising an elastic component, a mass block and at least one connecting frame, The connecting frame is provided with at least one vibration absorption cavity, at least part of the mass block is arranged in the vibration absorption cavity of the connecting frame, and the elastic component is arranged between the mass block and the wall of the vibration absorption cavity. The tuned mass damper is simple in structure, good in vibration and noise reduction effect, stable in performance, wide in application range, long in service life and high in cost effectiveness, and has little influence on the appearances of building structures. Further, the tuned mass damper with the frame can be widely applied to rail transit projects, large rotating equipment, airport boarding bridges, large-span passenger footbridges, harbor trestle bridges, high-rise buildings and other relative structures to control vibration and has wide market prospects.

Description

technical field [0001] The invention belongs to the technical field of vibration reduction of civil engineering structures and mechanical structures, and in particular relates to a tuned mass vibration damper used for controlling structural vibrations caused by the operation of transportation vehicles, machinery and equipment, and the like. Background technique [0002] In recent years, the rapid development of my country's rail transit has provided people with a fast and safe way of travel. At the same time, the vibration and noise problems generated by it have also seriously affected the quality of life of surrounding residents, endangered the safety of surrounding buildings, and made the track itself stable. Safety, safety and service life are also affected. [0003] With the development of urban construction, various high-rise, ultra-high-rise buildings, thin-height structures, and long-span buildings are increasing. At the same time, the urban transportation network is b...
