Influence of constant through-hole structure on low-speed characteristics of vehicle shock absorber

Abstract

The low-speed characteristics of vehicle shock absorber are mainly determined by the structural parameters of the constant through-hole on the throttle valve. By establishing the simulation model of the internal flow field of the shock absorber and using the method of computational fluid dynamics, the damping characteristics of the shock absorber at low-speed under different through-hole structures were obtained. The results show that when the volume of the constant through-hole of the throttle valve is equal, the damping force generated by the constant through-hole becomes larger and the throttling effect becomes stronger by increasing the number of steps or channels.
