摘要
通过分析半主动悬架的动力学特性,采用物理拓扑网络方式构建整车Simscape模型,建立整车半主动悬架动力学模型和路面输入模型,采用前馈控制策略调整半主动悬架减振器的阻尼力,通过与被动悬架系统的对比分析,结果表明:在典型的随机路面激振情况下,前馈控制方法能有效降低车身加速度,改善悬架系统适应道路的性能,提高了汽车的行驶平顺性。
By analyzing the dynamic characteristics of semi-active suspension,the Simscape model of the vehicle is constructed by physical topology network,and the dynamic model and road input model of semi-active suspension are established.The damping force of semi-active suspension shock absorber is adjusted by the feedforward control strategy.Through the comparative analysis with the passive suspension system,the results show that the feedforward control method can effectively reduce the body acceleration,improve the performance of the suspension system in adapting to the road,thus enhancing the smoothness of the car under the typical random road excitation.
