Problems solved by technology

The most obvious is that the general tuning system only conducts independent vibration reduction design for the vibration of the structure in a certain direction, and the effect of multi-dimensional vibration control, especially vertical and torsional vibration control is not good.
In addition, the cost of the tuning system is relatively expensive, which is not conducive to wide application

Embodiment Construction

[0022] The present invention will be further described below in conjunction with accompanying drawing:

[0023] Such as figure 1 , figure 2 As shown, this embodiment includes a top cover plate 12 , an outer wall sleeve 8 , and a sleeve structure arranged inside the outer wall sleeve 8 from top to bottom, an inner horizontal steel partition 10 and an outer horizontal partition 11 . All parts can be steel material or alloy material. The top cover 12 is connected with the upper structure, and the outer wall sleeve 8 is a cylindrical structure with a circular cross section, and its upper end surface is connected with the lower surface of the top cover 12 . The sleeve type structure includes the inner ring core tube 1, the outer ring core tube 4, the steel ball holder 3 and the steel ball 2. The inner ring core tube 1 and the outer ring core tube 4 have the same structure. The vertical direction is composed of rivets 7 superimposed and fixed together. The structure of the core ...

Abstract

The invention relates to a drum-type omni-directional turned mass damper, belonging to the technical field of vibration resistance and absorption in structural engineering, and comprising a top cover, an outer-wall sleeve connected with the top cover, a sleeve-type structure arranged inside the outer-wall sleeve, an internal horizontal baffle and an external horizontal baffle. The sleeve-type structure comprises an inner-ring core cylinder, an outer-ring core cylinder, a steel ball holder and a steel ball, wherein the inner-ring core cylinder is arranged in the outer-ring core cylinder, the outer surface of the inner-ring core cylinder is fixed with the steel ball holder that is internally equipped with the steel ball. A viscous damper is connected between the outer-ring core cylinder andthe outer-wall sleeve, the lower end faces of the inner-ring core cylinder and the outer-ring core cylinder are both connected with the internal horizontal baffle via a universal rolling spherical hinge, and a spring is connected between the internal horizontal baffle and the external horizontal baffle which is further fixedly connected with a substructure. The damper can be operable for turning energy consumption and vibration damping in all directions of the structure, namely, two horizontal directions, vertical direction, and two directions of reversing and swinging.

Description

technical field [0001] The invention relates to a drum-type omni-directional tuning mass shock-absorbing damper, which can be tuned and energy-consuming and shock-absorbing in all directions of the structure, that is, horizontal two directions, vertical directions, twisting and swinging two directions, and belongs to Seismic and shock-absorbing technical field of structural engineering. Background technique [0002] The ground motion during an earthquake is a complex multi-dimensional motion, and the period and phase of each point are different, resulting in the motion of each particle on the ground not only having a translational component but also a rotational component (a torsional component that rotates around a vertical axis and two components that revolve around a vertical axis). The swing component of horizontal axis rotation), the multi-dimensional characteristics of ground motion determine that the dynamic characteristics of building structures under earthquakes are...
