【摘要】 基于ADAMS/View,建立了考虑悬架运动学特性的非线性因素的1/4汽车悬架模型,并运用ADAMS/Hydraulic模块,建立了考虑液压元件的非线性特性的液压伺服控制系统,设计了液压伺服控制的主动悬架。以模拟路面和阶跃输入作为激励,采用PID反馈控制,且与被动悬架进行比较。仿真结果表明,该方法设计控制的主动悬架,其车身垂直加速度、悬架变形和车轮动载荷都明显降低。更多还原

【Abstract】 The quarter-car active suspension model with the nonlinear factor of kinematics characteristics was designed in ADAMS/View, and the hydraulic servo control system involving the nonlinear characteristics of the hydraulic component was designed in ADAMS/Hydraulic, so the active suspension with hydraulic servo control system was established. With simulated and jump as road input, under PID feedback control, and compared with passive suspension, the simulation results show that the body vertical acceleration, suspension distortion and wheel dynamic load are improved evidently.更多还原
