| Abstract: | As to the development of a vehicle, the rear cradle structure and bushing stiffness in the new 4 link rear suspension is optimized by the advanced optimization technique. The optimization result is obtained which can meet the requirements of vehicle dynamics, structure and NVH in the early development stage. Meanwhile, the application of multi objective optimization algorithm in the system is compared. The results can provide reference for the development of automotive chassis system. |
