摘　　要：文中对17自由度汽车动力学仿真的数学模型进行了分析,具体描述了该汽车动力学仿真模型微分—代数方程组的结构特征,并针对该结构特征提出了一种适用于在开发型驾驶模拟器上运行的求解算法。仿真实践证明,这种算法快速准确,并可应用到具有类似结构的汽车动力学仿真模型或其它多体系统微分—代数方程组的求解中。In the paper,the mathematical model of the17-DOF vehicle dyn amics simulation is analyzed.Structural features of the differential-algebraic equation set of the vehicle dynamics simulation model are described in detail, and a solving arithmetic which is suitable for the developing-type driving simu lator is presented in view of the structural fea-tures.It is proved by simulat ion that the arithmetic is quick and accurate,and can be applied to solutions o f other vehicle dynamic simulation models that have similar structures or other differential-algebraic equation sets of multi-body systems.
