| 摘 要： | 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。

| Abstract: | A five degree of freedom model of motor vehic1e vibration system and a set of state equations,based on band graph approach,are set up in this paper. The minimum sum of vibration energy of the vertical and pitching vibration and the minimum control power consuming are selected as the objective function,the control force of front suspension shock absorber of a vehicle is optimized by using the state feedback principle,then a computer simulation of vibration response for the case that the vehicle travels over an artificial triangular bump is carried out. The simulation results indicated that the severity of pitching vibration of vehicle with an active suspension can be obviously reduced. |
