本文应用键合图理论建立了汽车5自由度振动系统的键图模型并推导出状态方程，以垂直振动、纵向角振动能量最小和控制能量最小为目标函数，利用状态反馈原理代化出前悬架减振器的最佳控制力，对汽车驶过三角形单凸起时的振动响应进行了计算机仿真分析。结果表明，具有主动控制悬架的汽车，其纵向角振动得到明显的衰减。
In this paper, the bond graph theory is used to establish the key map model of the automotive 5-DOF vibration system and the state equation is deduced. Taking the vertical vibration, the minimum longitudinal vibration energy and the minimum control energy as objective functions, the state feedback principle is used to represent the front suspension The best control of the shock absorber, computer simulation analysis of the vibration response of the car when it passes through the triangle single bump. The results show that the vehicle with active control suspension has obvious longitudinal vibration attenuation.
