摘　　要：为抑制在路面不平激荡下半车车身的振动响应,以车身动能最小为控制目标,设计了半主动悬架控制器,对车身质心的垂直和俯仰方向进行控制并通过Matlab/Simulink搭建半车半主动悬架仿真模型并进行仿真。提取车身质心的垂直加速度、俯仰角加速度和悬架动挠度进行分析,仿真结果表明,相比被动悬架,该半主动悬架控制能有效地抑制车身垂直和俯仰方向的振动,提升了汽车的舒适性。In order to suppress the vibration response of the half-car body under the road incentive,with the minimum body kinetic energy as the control goal,the semi-active suspension controller is designed to control the vertical and pitch direction of the body center of mass,and the semi-car semi-active suspension simulation model is built and simulated through Matlab/Simulink.The vertical acceleration,pitch angle acceleration and suspension dynamic stroke of the body center of mass were analyzed.The simulation results show that the semi-active suspension control can effectively inhibit the vibration of the vertical and pitch direction of the body and improve the comfort of the car.
