摘　　要：为了提高汽车行驶平顺性以及安全性,以含主动悬架的4自由度振动结构力学模型为研究对象,采用状态空间的方法建立数学微分方程。将带修正因子的模糊控制器通过作动器将控制力施加给悬架系统,在白噪声路面模型激励下,应用MATLAB Simulink模块建立仿真模型,通过含主动悬架和被动悬架的振动分析,得到改进后的模糊控制算法对汽车行驶平顺性有明显的改善。该方法为含有主动悬架的汽车行驶平顺性研究提供了可行的方法。In order to improve vehicle ride comfort and safety, four-degree vibration structural model with active suspension is studied as a research subject, and a mathematical differential equation is established by means of state space. A fuzzy controller with a correction factor is applied to the suspension system by an actuator, under the excitation of white noise pavement model, the simulation model is established using MATLAB Simulink module, and the improved fuzzy control algorithm is obvious to improve the ride comfort of the vehicle through the vibration analysis of active suspension and passive suspension. Therefore, this paper provides a feasible method for the study of vehicle ride comfort which contains active suspension.
