An Active Suspension System Appplication in Multi-body Dynamics Software

Abstract

This paper describes the application of active suspension system in multi-body dynamics system software for ride comfort and road handling performance. In active suspension system, the most simulation software used by researchers is MATLAB/Simulink, ADAMS, and etc. For their ride quality test and road handling test. The concept of multi-body dynamics system software (CarSim) provides a real car specification based on the automotive engineering standard. The main parameters of active suspension system are the jounce or suspension deflection, damping force, wheel deflection, and velocity of the car body. The CarSim also provide various type vehicle selections especially for commercial car in different classes. The parameter setting in the CarSim is similar to the specification in the real commercial car. The results show the parameter response of active suspension system in different type of analysis.
