摘　　要：为建立贴合实际的汽车动力学模型,文章以国内某A0级轿车为研究对象,对整车及各零部件进行实际测量,以整车多体动力学软件ADAMS/Car为平台,建立了整车动力学模型。并对该模型的整车平顺性和操纵稳定性进行比对验证,验证结果表明:仿真结果和试验结果吻合较好,整车多体动力学模型基本正确,可以用来描述汽车在线性区和非线性区的动力学特性,为汽车试验场耐久性试验研究提供了良好的模型,也为后续研究奠定了基础。In order to establish accurate vehicle dynamics model,a domestic-made A0-class passenger car is used as object to measure its overall dimension and components dimension. Vehicle dynamics simulation model is set up using multi-body dynamics software ADAMS/Car. Ride comfort and handling stability of model are compared and verified with actual vehicle. The simulation are in good agreement with the test result, the model established using multi-body dynamics is nearly accurate, which can show the dynamics property both in linear area and nonlinear area, and providing a better foundation for testing durability in vehicle test site.
