The multiobjective optmi ization sofwt are iSightFD andmultibody dynam ics smi ulation softw areAdam s/ carwere used to joint optmi ization, the evaluation standard of the ride and the stability of the carw as optmi ized by using the island of genetic algorithm s, The optmi ization results show s that the ride and the stability are mi proved of the car. Multiobjective optmi ization of evaluation the performance of the car is balanced and optmi izated, then effectively solved the contradictions problem between the ride and the stability of the car.
