A rigid-elastic coupling multi-body dynamic model of a car was established. The controllability and stability including constant cornering, steering returnability and steering effort performances are analyzed. Results show that there is still a feasibility to enhance the understeer. By optimizing the suspension parameters using DOE method, the characteristic of understeer was improved. Simulation analysis indicated that the characteristics of steering effort and steering returnability were not affected due to change of suspension parameters.
