车辆主动悬挂系统建模与性能仿真

Active Suspension System Modeling and Performance Simulation for Vehicles

提高车辆悬挂系统的悬挂性能 ,是减缓车辆行驶中受到的撞击震动、提高车辆行驶平顺性和工作可靠性的重要途径 .该文通过建立主动悬挂系统模型 ,运用超前补偿的伯德图设计方法进行设计 ,并对其进行了计算机仿真和结果分析 ,通过与传统的被动悬挂系统相比较证明 ,其性能明显优于被动悬挂系统 .

To improve the performance of suspension system is the main way to dissipate the road disturbance and improve the ride and safety.This paper simulates the active suspension system and analyses the test results through establishing an active suspension system mode with a design method based on bode of feedback head-controller.Compared with conventional passive suspension,the results show that it is superior to the passive suspension in performance.
