Abstract
A closed-loop dynamic simulator based on Adams and Matlab/Simulink software is modelled in this paper for active suspension systems to shorten the developing period, in which the active suspension system dynamic model and its control method are validated. A detailed 3D model of half-car active suspension system with hydraulic actuator is firstly built by using Solidworks. And then the virtual prototype of half-car active suspension system is established in Adams. Moreover, the proportion integration differentiation (PID) control method is designed to regulate the vehicle vertical displacement and pitch motion in Matlab/Simulink software. Finally, we combine the Adams and Matlab/Simulink software together to build a dynamic simulator, in which the correctness of the active suspension system dynamic model and effectiveness of the PID control method can be demonstrated.
