摘要：
To further improve the damping performance of automobile suspension, the structure and parameters of automobile suspension are optimized. Based on the electromechanical similarity theory, a suspension structure of hybrid connected vehicle with spring, damper and inerter is proposed, and the multi-objective genetic algorithm is used to optimize the parameters of vehicle suspension damping system. By solving the dynamic equation, the vibration response of vehicle suspension damping system under road pulse excitation is analyzed in time domain, and the influence of parameter optimization on suspension damping performance is analyzed in frequency domain. The results show that, compared with the traditional vehicle suspension, the proposed hybrid connected vehicle suspension structure can effectively reduce the resonance peak of the vehicle damping system and improve the damping performance of the vehicle suspension. Compared with the initial design parameters, the parameters obtained by using the multi-objective genetic algorithm can further improve the damping performance of the vehicle suspension. © 2021, Editorial Department of Journal of Northeastern University.
