Intelligent self-adaptive vibration reduction system

Abstract

The invention belongs to the technical field of vibration reduction, and discloses an intelligent self-adaptive vibration reduction system. The system comprises an outer sleeve composed of a U-shapedplate and a metal outer frame; the two sides of the U-shaped plate are embedded in the metal outer frame, and the interior of the U-shaped plate is connected through a crossed pressure-resistant plate; the middle parts of the crossed compression-resistant plates are hinged; the middle parts of the crossed clamping and pressing plates are respectively connected with the U-shaped plate and the metalouter frame through first damping springs; second damping springs are symmetrically welded to the left side and the right side of the crossed compression-resistant plate. Four end parts of the crossed pressure-resistant plate are in sliding connection with the U-shaped plate and the metal outer frame through sliding blocks and limiting springs respectively. The system is simple in structure and convenient to machine, and the elastic potential energy of the damping spring and the limiting spring, the friction force of the damping plate, the air compressibility of the air spring structure, theviscosity change of magnetorheological fluid in the magnetorheological damper, the repulsion effect of the electromagnet and the like are utilized; therefore, the vibration reduction system has the advantages of being good in vibration reduction effect, high in reliability and capable of achieving autonomous control.

Description

technical field [0001] The invention relates to the technical field of vibration reduction, in particular to an intelligent self-adaptive vibration reduction system, which is used in the vibration reduction field of rail traffic such as subway stations. Background technique [0002] At present, rail transit has become the key development target of countries all over the world due to reasons such as convenience, environmental protection, punctuality, and speed. Soon rail transit has problems such as loud noise, low comfort, and train vibration affecting surrounding buildings. Most of the damping devices that have been put into use are steel spring dampers, liquid dampers, friction dampers, etc. When they reduce vibration, there is still the problem of continuous vibration on the damper when the vibration of the train is transmitted to the damper , these vibrations have an adverse effect on the comfort of the vehicle and the service life of the building. Therefore, developing...
