摘　　要：运用多体动力学方法建立了某款轻型客车整车操纵稳定性仿真模型,设计试制了一款磁流变阻尼器,作为该客车的减振器并通过试验建立其数学模型。以整车操纵稳定性及行驶平顺性为目标提出了一种基于PID神经网络的协调控制策略,实现了汽车半主动悬架与转向系统之间的良好匹配和协调。仿真结果表明,所提出的协调控制策略,在有效改善车辆的操纵稳定性的同时兼顾了车辆的行驶平顺性。A model for the simulation on the handling and stability of a light bus is built by using multi-body dynamics scheme.A magneto-rheological damper is designed and trial produced dedicated for the shock absorber of that bus,with its mathematical model set up based on test data.With both the handling stability and ride comfort of vehicle as objectives,a coordinated control strategy based on PID neural network is proposed to achieve the good matching and coordination between the semi-active suspension and steering system of vehicle.The results of simulation show that the coordinated control strategy proposed effectively improves the handing and stability with good ride comfort of vehicle.
