摘　　要：以多体系统动力学理论为基础,应用机械系统仿真分析软件ADAMS,创建空气悬架客车前悬架、后悬架的多体系统动力学模型,包括转向系、发动机、车身、前后轮胎等在内的整车虚拟样机模型。并通过编制路面谱文件对虚拟模型进行平顺性仿真和悬挂系统固有频率仿真试验,结果显示该车的平顺性能比较理想。将仿真结果与样车道路试验结果进行对比,发现二者比较吻合,从而验证了所创建的虚拟样机模型的可靠性。研究结果表明虚拟试验可以有效地分析汽车的平顺性。Based on the theory of multi-body system dynamics and with application of mechanical system simulation software ADAMS, the multi-body system dynamic models of front and rear suspensions of air suspension bus were established. The established models of vehicle virtual prototype includes the models of steering system, engine, body, front and rear tires, etc. With help of the stochastic road input document, the ride comfort and the natural frequency of air spring suspensions of the virtual model were simulated which shows that ride comfort performance is good. The simulation result was compared with road test result of vehicle sample, which verified the reliability of the virtual prototype model. The research shows that virtual test for analyzing ride comfort of vehicle is effective.
