Abstract: The unequal length independent double crossarm suspension has excellent handling stability, but the structure is complex and the cost is high, and it has a broad market in high-end cars and racing cars. This paper aims to optimize the design of the front suspension of the electric racing car by using ADAMS simulation software. By building an independent front suspension model with unequal length and double cross arms, the relevant parameters are checked and the simulation analysis is carried out, and the changing trend of the positioning parameters is deeply studied. Based on the analysis results, the front suspension design is successfully optimized and the handling stability of the car is improved. This research not only provides a theoretical basis for the optimization of the front suspension of the racing car, but also brings technological innovation to the high-end automobile and racing market, and shows the feasibility and effectiveness of the optimization design.
