【Abstract】 Based on the principle of multi-body system dynamics of vehicle and optimized design, the paper brought forward an approach of optimizing the main parameters and system stiffness design of suspension in vehicles, which can meet the demand of both the manipulating stability and the smoothness of vehicles. Three-dimension digital mode of twin-wishbone independent suspension and the complete vehicle was established on the virtual prototype machine, and the validity of the approach of the optimized design was validated by carrying through the emulating examinations.更多还原
