为解决车辆滚翻研究过程中有限元仿真面临的计算效率和精度问题，参照美国FMVSS208平台车试验条件，分别进行了车辆滚翻多刚体动力学和有限元仿真研究.基于滚翻过程中车辆运动姿态对两种仿真方法之间进行运动学数据交换，形成面向车辆滚翻的运动姿态协同仿真方法.结果表明，该方法可以利用多刚体动力学仿真替代有限元仿真中部分运动学计算过程，在有限元仿真精度基础上提高有限元仿真效率，为研究车辆滚翻安全性提供了新的思路和技术途径. 

Research on Collaborative Motion Simulation Environment for Vehicle Rollover

In order to solve the problem of computational efficiency and accuracy of finite element simulation in vehicle rollover research, multi-rigid-body dynamics and finite element simulation of vehicle rolling were carried out respectively based on the test conditions of FMVSS208 platform vehicles in the United States. Considering the kinematic data exchange between the two simulation methods of vehicle movement attitude in the rolling process, a cooperative simulation method of the motion attitude of vehicle rolling was presented. The results show that the method can take the advantage of multi-rigid body dynamics simulation to replace some kinematic calculation process in finite element simulation, improve the efficiency of finite element simulation on the basis of finite element simulation accuracy, and provide a new technology way for the study of vehicle rollover safety.
