A New Kind of Semi-Active Suspension Magnetorheological Fluid Shock Absorber Damping Force Model

Peng Sun, Jianfeng Wang, Feng Feng

Abstract

Based on the damping characteristics, design a kind of magnetic fluid shock absorber, and the damping force theory formula, derived from the damping force of the formula can be that, according to the design of shock absorber, in the vehicle suspension on the dynamic performance simulation test for the damping-displacement characteristic and speed characteristics is verified by experiments, the proof is in the formula of the damping force of the damping force and the polarization current into nonlinear (secondary) relationship is reasonable, to design the actual shock absorber to really have a certain reference value.Intorduction
