| 摘 要： | 为缓和路面传递给车身的冲击，改善汽车行驶的平顺性和操作稳定性，文章建立了二自由度1／4车体半主动悬架非线性动力学模型，利用MATLAB模糊逻辑控制工具箱设计半主动悬架的模糊控制器，通过运用MATLAB／SIMULINK，对悬架系统进行了仿真分析。结果表明，该控制方法能有效地降低车身垂直加速度、悬架的动挠度和车轮动载荷，提高了汽车的平顺性和操纵稳定性。

| Abstract: | In order to ease up the body impact brought by road, improve automotive smoothness and operation stability, semi-active suspension nonlinearity dynamic model of a two degree freedom 1/4 body is built. Based on MATLAB fuzzy logic control cabinet, semi-active suspension fuzzy controller is designed. Simulation analysis of suspension system is proceeded by using MATLAB/SIMULINK. The result shows that this control method can reduce the body vertical acceleration, suspension distorsion and tire loads effectively, and improve automotive smoothness and operation stability. |
