| 摘 要： | 由于车辆行驶状况复杂多样，传统静态工况无法复现各类恶劣路况下后底盘转向节真实应力，因此在利用MotionView建立整车刚柔耦合多体动力学模型的基础上，将后转向节利用柔性体进行模拟；在进行虚拟试验场仿真分析的同时采用模态综合法计算结构动应力，得到后转向节最高应力位置及发生时刻.仿真结果与整车道路试验结果的对比表明仿真方法准确.

| Abstract: | Due to the complex vehicle driving conditions, the actual stress of chassis steering knuckle under various bad road conditions can not be forecasted correctly by the traditional static load conditions. A rigid flexible coupling multi body dynamics model is built by MotionView, in which the rear steering knuckles are simulated as flexible bodies. The virtual proving ground simulation analysis is done while the dynamic stresses are calculated by modal synthesis method, and the location and occurring time of maximum stresses of rear steering knuckles are identified. The comparison between simulation results and the results obtained by road test for whole car shows the correctness of the simulation method. |
