Abstract: The size of the non-spring mass of the vehicle has a greater impact on the performance of the car, and the empirical calculation method is used to obtain the unsprung mass of the whole vehicle in the research and development and design of the vehicle, and the non-spring mass is verified and corrected according to the spring preload force and the weight of the whole vehicle in the real vehicle stage. In order to improve the accuracy of the calculation and analysis of non-spring mass in the pre- development and design stage of the whole vehicle, this paper takes the common McPherson suspension and torsional beam suspension as an example, and uses Adams/Car software to analyze the non-spring mass contribution of key chassis parts, and the analysis method and analysis conclusion can provide a certain reference basis for the calculation and analysis of the unreed mass of a specific model in the R&D and design stage of the automobile.
