基于车辆悬架系统功率流分析的改进型SH-ADD控制策略仿真研究OA

To reduce the sprung mass acceleration across the full frequency domain,thereby improving vehicle ride comfort,it fo-cuses on a semi-active suspension equipped with a Continuous Damping Control(CDC)damper.By integrating the advantages of the continuous Skyhook(SH)control strategy and the acceleration damping control(Active Dynamic Damper,ADD)strategy,and based on a power flow analysis of the vehicle suspension system,an enhanced SH-ADD control strategy is proposed.This strategy combines the strengths of both SH and ADD.A CDC damper is selected as the semi-active component of the suspension,and a quarter-car model is established.Using sinusoidal excitation and random road surfaces as inputs,simulations are conducted in Simulink.The proposed control strategy is compared with passive suspensions and other control strategies.The results demon-strate that the improved SH-ADD control strategy,based on power flow analysis of the vehicle suspension system,exhibits signifi-cant superiority and effectiveness in reducing sprung mass acceleration,thereby enhancing vehicle ride comfort.
