摘要
建立了1/4车体二自由度的液压半主动悬架模型及动力学模型,设计了用于该半主动悬架的模糊控制器,应用Matlab/Simulink控制系统仿真软件,以正弦信号作为路面输入信号对1/4汽车液压半主动悬架模型进行计算机仿真。仿真结果表明具有此模糊控制器的半主动悬架在提高车辆乘坐的舒适性和操纵的稳定性方面明显优于被动悬架。
The two - degree of freedom semi - active hydraulic suspension model for a quarter of vehicle is built up, then the designing way of automobile hydraulic semi - active suspension with fuzzy controller is introduced in fuzzy system. The comparison study through simulation by using MATLAB/Simulink shows that the performance of hydraulic semi - active suspension with fuzzy controller is better than that of passive suspension. It is a successful example of semi - active suspension in vehicle design application.
