Abstract

The invention discloses an array damping-ball shock absorption device. The array damping-ball shock absorption device comprises a vertically arranged shock absorption main body and a shock absorption shaft matched with the shock absorption main body, wherein the shock absorption main body comprises an outer sleeve with both a top cover and an outer sleeve base, and the shock absorption shaft and the outer sleeve are coaxially arranged; an upper space and a lower space of the outer sleeve, separated by a lug boss arranged at one end of the shock absorption shaft, are filled with damping balls respectively; and coaxial connecting pieces are arranged on the outer wall of the upper end of the outer sleeve. According to the shock absorption device, by virtue of the extruding plastic deformation and mutual rubbing effects between the balls, the energy dissipation effect of the shock absorption device is improved, and accordingly, the shock absorption performance of the shock absorption device can be improved.

Description

technical field [0001] The invention relates to a shock absorbing device, in particular to an array type damping ball shock absorbing device. Background technique [0002] Seismic loads are likely to cause damage to electrical equipment, resulting in interruption of power supply, affecting post-earthquake rescue, and causing huge losses to the national economy. The shock absorber uses passive energy dissipation technology to absorb the energy input by external earthquakes, thereby improving the seismic performance of electrical equipment. However, with the increase in earthquake magnitude and the increasing weight and stiffness of electrical equipment, it is required that the energy dissipation capacity of the shock absorbing device and its own stiffness be enhanced accordingly. [0003] How to improve the energy dissipation capacity of the shock absorber is the frontier direction of the design of the shock absorber. In order to maximize the shock absorbing capacity of the ...
