Abstract

Established the electrorheological dampers semi-active suspension system 1/4 vehicle dynamics model, and gives out the suspension system equation of motion and state equation. The stochastic optimal control theory is applied to the control of vehicle suspension of vehicle suspension tires deformation, suspension deformation, body acceleration simulated. In vibration comfort improvement at the same time, suspension spring deformation increase and rational selection of system parameters for the automotive dynamic provides theoretical basis for designing.
