Abstract

The invention relates to a collision gap self-coordination device. The collision gap self-coordination device comprises a fixed chassis, a fixed rod part, a reset sliding block, multiple limiting plates, and multiple movable edge plates; the upper end of the fixed rod part is fixed to the lower end of the fixed chassis, a reset spring is arranged on the fixed rod part, the reset sliding block is arranged on the fixed rod part in a sleeving manner and is connected to the upper portion of the reset spring, a collision cavity is defined by the limiting plates, the fixed chassis is located on thebottom of the collision cavity, the lower ends of the limiting plates are hinged to one ends of multiple supporting parts, the other ends of the supporting parts are hinged to the reset sliding block,one ends of the movable edge plates are in sliding connection to the limiting plates, and the other ends of the movable edge plates are hinged to the fixed chassis. The self adjusting of the optimalcollision gap of a damper under different motivations can be achieved, the motivation strength self adaptation is achieved, a vibration reducing frequency band is wide, robustness is achieved, according to the magnitude of the exciting loads, the collision gap self-adaptation adjusting is achieved, poor vibration of the structure in the horizontal direction is reduced, and the vibration reducing effect is greatly improved.

Description

Technical field

[0001] The invention belongs to the field of civil engineering structure vibration control, and specifically relates to a collision gap self-coordination device. Background technique

[0002] With the rapid development of the social economy, the size of the building structure is increasing, from high-rise buildings to super high-rise buildings. At the same time, the threats to high-rise buildings such as earthquakes and wind loads are increasing day by day. In recent years, in previous major earthquakes and wind disasters, accidents of structural collapse and damage have occurred from time to time, and economic losses are incalculable. Therefore, the development and application of structural vibration reduction technology is an inevitable trend.

[0003] Passive control technology has the characteristics of maturity, high cost performance, high reliability and easy maintenance, and is widely used in structural vibration reduction. Among them, the collision damper...
