摘　　要：悬架系统是一个复杂的动力学系统,其模型的精确性、合理性对主动悬架的研究起到决定性作用。为进一步满足车辆乘坐舒适性的要求,以整车模型为研究对象,运用八板块方法进行动力学分析,根据牛顿运动学定律推导出悬架各部分的力学微分方程,从而建立了包含俯仰运动模型、侧倾运动模型和转向运动模型的整车模型,为车辆主动悬架的进一步研究提供了理论基础与依据。Suspension system is a complicated dynamic system. The accuracy and reasonableness of the mathematical model play a decisive role. For further meeting the requirements of vehicle ride comfort, we choose overall vehicle which has carried on the dynamics analysis as the research object, and the mechanical differential equations of suspension parts are deducted according to Newton＇s Laws of Motion in this paper Finally, a complete vehicle model containing pitch model, roll model and steering model is established, which provides theoretical basis for the further study of automotive active suspension.
