Description

Technical Field

[0002] A damper is a device that dissipates motion energy by providing resistance to motion. Various dampers (or shock absorbers) have long been used in industries such as aerospace, aviation, military, guns, and automobiles to reduce vibration and dissipate energy. Since the 1970s, people have gradually transferred these technologies to structural engineering such as buildings, bridges, and railways. Viscous damper: It is made based on the principle that fluid movement, especially when the fluid passes through a throttling hole, will generate throttling resistance. It is a damper related to the speed of piston movement. It is widely used in high-rise buildings, bridges, seismic reconstruction of building structures, anti-vibration of industrial pipeline equipment, military industry, etc. Patent: CN 110822004A discloses a viscous damper, including: a piston cylinder, in which a damping medium is contained; and a piston, which is arranged in the piston cylinder and can slide in the piston cylinder along the length direction, wherein a main flow hole is constructed on the piston and passes through the piston in the length direction, and the main flow hole is inclined relative to the length direction, so that the damping medium passing through the main flow hole can drive the piston to rotate in the piston cylinder.
