中文摘要:
      为提高某新能源汽车转向系统可靠性,对其转向内拉杆球绞及螺纹连接部位强度进行了研究。在ADAMS/CAR中搭建虚拟试验台,得到转向拉杆受到的最大转向力;将简化后的转向拉杆连接部位模型导入ANSYS Workbench中,生成有限元模型,分别建立螺纹和球绞连接摩擦接触,通过仿真得到应力分布,实现球绞连接和螺纹连接的模拟效果。仿真结果表明转向拉杆连接位置的工作应力均小于许用应力,强度满足使用要求。
英文摘要:
      In order to improve the reliability of the steering system of a new energy vehicle, the strength of the ball joint and the threaded joint of the steering inner rod was studied. A virtual test rig was built in ADAMS/CAR, and the maximum steering force of the steering rod was obtained. The model of the connection point of the simplified steering rod was introduced into ANSYS Workbench to generate a finite element model. Thread and ball joint frictional contact were established respectively. The stress distribution was obtained by simulation, the simulation effect of the connection of the ball joint and the connection of the thread was realized. The result showed that the working stress at the joint position was less than the allowable stress, and the strength met the requirements for use.
