摘　　要：汽车动力学包括对一切与车辆系统相关运动的研究,其最核心的是平顺性和操纵稳定性这两大领域。在简要说明了汽车动力学发展过程的基础上介绍了平顺性和操纵稳定性两大领域的模型发展过程。平顺性模型主要经过集中质量—弹簧—阻尼模型、有限元模型和动态子结构模型阶段;而操纵稳定性模型从低自由度线性模型、非线性多自由度模型发展到多体模型。最后提出了汽车动力学仿真模型的发展动向。Vehicle dynam ics studies all movements re le vant to vehicle system and its core is the two fields of ride-ability and han dling stability.In the paper,developing process of models of vehicle rideabili ty and handling stability are in-troduced after development course of vehicle dynamics is simply introduced.Rideability models develop from the mass-spring-damping model to the finite element model and the dynamic sub-structure mode l.The handling stability models de-velop from the low-freedom linear model to nonlinear multi-freedom model and then to the multi-body model.In the end,d eveloping direction of vehi cle dynamic simulating model is pointed out.
