Abstract

The electric vehicle industry has witnessed significant growth in recent years, prompting heightened research interest in its various components. The suspension system, serving as a critical power-transmitting device between the frame and the axle, has garnered particular focus. This system is pivotal in meeting the dual performance objectives of ensuring driving smoothness and enhancing maneuvering stability. Accordingly, this study investigates the structural types of suspension systems and advances the design of a suspension guiding mechanism specifically tailored for electric vehicles. At the same time, the dynamic model of active suspension is constructed, and the algorithm for optimizing and establishing the active suspension system for electric vehicles is used. The simulation experiments on the suspension system, the control optimization method of the system in this paper’s car body spring loaded mass acceleration response, dynamic deflection ring, and the control input are stable between -0.4~0.5m/s², -0.005~0.01m and the suspension system’s between -0.7~0.6N, respectively. Moreover, the car body displacement and speed are gradually stabilized at about ±0 compared to the motion speed. In this paper, the suspension system can effectively solve the problem of automobile damping control and reduce the impact suffered by the body so as to improve the smoothness of the body in the process of driving and the operation of the stability of the new for the development and improvement of the suspension system in the electric vehicle industry to provide a reliable method.
