Embodiment Construction

[0024] Embodiments of the present invention will be described in detail below in conjunction with technical solutions and accompanying drawings.

[0025] The suspension type multi-dimensional collision damper proposed by the present invention is as follows: figure 1 , figure 2 As shown, the shock absorber of the device is composed of a tuned mass damper and a suspended mass pendulum.

[0026] The suspended mass pendulum consists of a universal hinge 1, a rigid suspension rod 2, and a mass ball 4;

[0027] The vertical shock absorber, that is, the tuned mass damper is composed of four springs 8 and four liquid viscous dampers 7, an upper circular plate 10 and a partition 9, an inner metal box 5 and a mass ball 4 inside the box.

[0028] The outer container box 6 is suspended or installed on the top of the structure, and the inner metal box 5, the spring 8 and the liquid viscous damper 7 are connected to the upper circular plate through a rigid connecting rod, and the rigid c...

Abstract

The invention discloses a suspension type multidimensional impact vibration reduction damper which comprises an external container box. A partition plate with a circular hole is horizontally arranged in the external container box and divides the external container box into two spaces, fluid viscous dampers and springs are arranged on the partition plate, the upper ends of the fluid viscous dampers and the upper ends of the springs are connected with a circular plate which does not make contact with the external container box, the lower ends of the fluid viscous dampers and the lower ends of the springs are connected to the partition plate, the center of the circular plate is provided with a rigid connecting rod which penetrates through the circular hole in the center of the partition plate and is connected with an internal cylinder box, the bottom end of the rigid connecting rod is connected with an internal metal box, a rigid hanging rod is arranged in the internal metal box, and the bottom of the rigid hanging rod is connected with a mass ball. The suspension type multidimensional impact vibration reduction damper can reduce the multidimensional vibration response of a structure under the action of an earthquake or a wind load and can effectively make up for the hidden danger brought by the uncertain direction when a load is generated.

Description

technical field [0001] The invention is a suspension type multi-dimensional collision vibration reduction damper, which is mainly aimed at the multi-dimensional collision vibration reduction device of some complex or important engineering structures and towering building structures. Background technique [0002] With the development of society, the forms of engineering structures are increasingly diversified and the application of lightweight and high-strength materials, the stiffness and damping ratio of the structure become smaller. Under the action of strong wind or strong earthquake, the dynamic response of the structure is strong, and it is difficult to meet the structural comfort. and security requirements. How to make buildings have good anti-seismic and wind resistance, and reduce the damage caused by wind load and earthquake to buildings has become a research hotspot in the field of civil engineering, and has attracted more and more attention. Structural vibration c...
