A Multi-stage Adjustable Particle Damping Inertial Capacity Shock Absorber

Abstract

The invention discloses a particle damping inertia shock absorber with multi-stage adjustment, which comprises a bottom plate and a metal shell with an open bottom, and the metal shell can slide horizontally on the bottom plate; a plurality of limiters are horizontally arranged in the metal shell. The position shaft, the limit shaft is pierced with a roller, the two ends of the roller are fixedly connected with gears, and the two sides of the bottom plate are fixedly provided with racks capable of meshing with the gears; the two ends of the bottom plate are symmetrically provided with Two fixed spring plates, the outer end surfaces of the fixed spring plates are fixedly equipped with springs, the ends of the springs are fixedly connected to the two ends of the metal casing, and earrings are fixedly arranged on the outer sides of the two ends of the metal casing, and the earrings are used for connecting External structure and dampers. The particle damping inertial capacity shock absorber with multi-stage adjustment provided by the invention can produce different inertial capacity effects and realize multi-stage vibration reduction. At the same time, since the present invention adopts the form of particle damping, the vibration damping frequency band can be widened.

Description

technical field [0001] The invention relates to the field of energy consumption shock absorption of civil engineering structures, in particular to a multi-stage adjustable particle damping inertia shock absorber. Background technique [0002] Energy dissipation and shock absorption technology, that is, a technology to reduce the structural vibration response by adding energy dissipation and shock absorption devices at the position where the structural vibration response is relatively large. When a strong earthquake or strong wind causes the structure to vibrate violently, the energy-dissipating shock-absorbing device can use self-generated characteristics, such as hysteresis deformation, yield deformation, friction, etc., to consume a large amount of energy input by the earthquake or strong wind, which greatly reduces the structure. Excellent vibration response ensures structural safety, comfort and performance requirements for normal use of internal devices. [0003] As a ...

Problems solved by technology

In the existing research, the mass characteristics of the inertial unit, the stiffness of the spring unit, and the damping coefficient of the damping unit are generally fixed values, which have obvious linear characteristics, so they cannot meet the requirements of different vibrations of different intensities or different damping forces under different projects. needs
