Abstract : The RMS of weighted acceleration, wheel dynamic load and suspension dynamic deflection are determined as evaluation indices of vehicle ride comfort performance. A multi-body dynamic rigid-flexible coupling model of an in-wheel motor vehicle is built based on the multi-body system dynamics. The ride comfort results of ride comfort simulation and road test are well fitted. A kriging model is created to describe the relationship of vehicle ride comfort evaluation indices and suspension parameters. A multi-objective optimization using NSGA-II is processed using this model, and the vehicle ride com
