【Abstract】With the development of the times，people's requirements for car comfort have also increased，and interior noise is one of the key issues that people pay attention to. The article mainly discusses multi-objective optimization of bushings based on vehicle road noise. By analyzing the sensitivity of the bushings，the bushings with a large contribution to road noise are identified，and the correction coefficient of the bushings is analyzed，providing reference for the early design and development of vehicle road noise.

【Key words】road noise；chassis bushing；multi objective optimization；sensitivity
