【Abstract】 The four-link type suspension is an advanced suspension type.In this paper,the multi-body system model of the four-link type suspension is set up,and the characteristics of wheel alignment parameters are simulated.The structural parameters of the suspension are optimized by using the method of the multi-objective function.The kinematic performance of wheel alignment after optimization is compared with that before optimization,which indicates that optimization of the structural parameters of suspensions is very helpful to the improvement of characteristics of suspensions.更多还原
