| 摘 要： | 建立了汽车磁流变半主动悬架1/4车辆模型的基础上,采用模糊控制策略,对半主动悬架进行模糊控制仿真。粘滞阻尼系数是磁流变阻尼器的重要参数之一,为研究其对悬架性能的影响,在Simulink环境下采用多次对粘滞阻尼系数赋值的方法,分别对半主动悬架簧载质量加速度、悬架动行程和轮胎动载荷的均方根值进行了仿真计算,得到了粘滞阻尼系数对悬架性能的影响曲线。结果表明：调节粘滞阻尼系数可使簧载质量加速度均方根值达到最小值;增大粘滞阻尼系数可使悬架动行程和轮胎动载荷减小。粘滞阻尼系数为定值时对半主动悬架和被动悬架进行了仿真对比。

| Abstract: | Based on a 1/4 vehicle model with magnetorheological semi active suspension, a fuzzy control simulation model of semi active suspension is built with the fuzzy control strategy.As one of the important parameters of magnetorheological damper,viscous damping has some impact on suspension performances.To prove that impact, the rms of sprung mass acceleration,suspension travel and tire load of semi active suspension are emulated individually in the Simulink environment with assigning viscous damping repeatedly. The results show that the rms of sprung mass acceleration could reach the minimum by regulating viscous damping,and increasing viscous damping could reduce suspension travel and tire load.With a certain value of viscous damping,the performances of semi active suspension and passive suspension are compared. |
