Problems solved by technology

[0004] The output range of the shear valve magnetorheological damper is related to the structural parameters of the damper. After the structural design is completed, the output range will be fixed, making it impossible to change in a wide range, thus limiting the use of the damper.

Abstract

The invention relates to a shear valve type magnetorheological damper and a parameter optimization method thereof. The shear valve type magnetorheological damper comprises an outer cylinder barrel (4A), inner cylinder barrels (4B), a piston rod (7), a piston (6A), coils (5) and magnetorheological fluid (3). The number of the inner cylinder barrels (4B) is multiple. The inner cylinder barrels (4B) are the same in outer diameter and height and different in thickness. Piston rings (6B) are installed at the end of the piston (6A) and can be disassembled and replaced. The number of the piston rings (6B) is multiple. The piston rings (6B) are the same in inner diameter and outer diameter and different in thickness. According to the shear valve type magnetorheological damper, the force output range of the damper is adjusted by replacing the piston rings different in thickness and the inner cylinder barrels different in thickness, the effects of being simple and reliable are achieved, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of magnetorheological dampers, in particular to a shear valve type magnetorheological damper and a parameter optimization method thereof. Background technique [0002] Vibration can cause some very serious consequences such as the failure of mechanical parts, the collapse of bridges, or the deterioration of workers' environment. Therefore, shock absorbers are usually used in industries such as automobiles, buildings, bridges, and railways to reduce shock absorption. There are also various shock absorbers used in various industries. According to the required control force and energy input, shock absorbers are divided into active shock absorbers, semi-active shock absorbers and passive shock absorbers. Among them, passive shock absorbers can no longer satisfy the generality of their shock absorption effect. People have higher requirements for shock absorbers, and active shock absorbers have not been widely us...
