摘　　要：汽车悬架系统作为车轮与车架之间的连接装置,对汽车平顺性起到重要作用。本文针对汽车非线性悬架系统控制问题,引入阻尼力与弹簧弹性变化关系,建立弹簧弹性系统,利用Carsim与Matlab软件联合仿真,结果表明所建立的悬架滑模控制方法对汽车车身振动有较好的控制效果。The car suspension system,as a connecting device between the wheels and the frame,plays an important role in the smoothness of the car.This article focuses on the control problem of nonlinear suspension systems in automobiles,introduces the relationship between damping force and spring elasticity changes,establishes a spring elasticity system,and uses Carsim and Matlab software for joint simulation.The results show that the established suspension sliding mode control method has a good control effect on vehicle body vibration.
