A Multiple Shock Absorber Based on Magnet Performance

Abstract

The invention discloses a multi-damping device based on magnet performance. The multi-damping device based on the magnet performance comprises an outer cylinder, and an upper layer plate, a middle layer plate, and a lower layer plate are horizontally arranged on the inner part of the outer cylinder sequentially from top to bottom; the upper layer plate and the lower layer plate are fixed to the upper inner wall of the outer cylinder and the lower inner wall of the outer cylinder correspondingly; the inner part of the middle layer plate is hollow, a plurality of separating plates are arranged in the inner part, and spaces formed between adjacent separating plates are provided with a moderate amount of particles; magnet sets are arranged between the upper layer plate and the middle layer plate and arranged between the middle layer plate and the lower layer plate; rigid rods are horizontally arranged on the left side and the right side of the middle layer plate and connected to the middlelayer plate, first sliding wheels are arranged at the other ends of the rigid rods, and the first sliding wheels are located on a first guiding rail; arranged direction of the first guiding rail is perpendicular to the rigid rods, and second sliding wheels are arranged at the two ends of the first guiding rail, and the second sliding wheels are located on a second guiding rail; the two ends of the second guiding rail are fixed to the inner wall of the outer cylinder; and springs are arranged all around the middle layer plate.

Description

technical field [0001] The invention belongs to the field of vibration control of civil engineering, in particular to a multi-vibration absorber based on the performance of magnets, which is mainly used in controlling the vibration response of high-rise buildings and towering structures. Background technique [0002] With the development of social economy and urbanization, buildings present a trend of super high-rise and large-span development. For these complex building structures, vibration problems such as earthquake resistance and wind resistance become the key to affecting normal use and ultimate bearing capacity. However, due to the uncertainty of external excitation, the traditional method of relying on the energy dissipation capacity of components to passively absorb external input energy cannot meet the anti-vibration requirements of building structures, and has great limitations. Studies in recent years have shown that installing dampers or vibration reduction dev...

Problems solved by technology

However, particle dampers, eddy current dampers and negative stiffness dampers all have many disadvantages when working alone

Particle dampers and eddy current dampers have a certain time lag in application, and it is difficult to obtain a good vibration reduction effect under the action of earthquake or wind load
