摘要
为了提升电动汽车转向的安全性,通过有限元法对汽车冗余转向系统关键零件性能进行了研究。研究发现,设计冗余转向系统关键零件具有良好性能,齿轮传动机构、蜗轮减速机构及转向器壳体的强度与刚度均在规定范围内。通过实践应用进一步验证了设计冗余转向系统的良好性,将其应用到电动汽车当中后,可降低转向系统的故障概率,有利于提升电动汽车行驶的安全性与稳定性。
In order to improve the safety of electric vehicle steering,the performance of key parts of automobile redundant steering system was studied by finite element method.It is found that the key parts of the design redundant steering system have good performance,and the strength and stiffness of the gear transmission mechanism,the worm gear reduction mechanism and the steering gear housing are all within the specified range.The practical application further verifies the goodness of the design redundant steering system,which can reduce the failure rate of the steering system and improve the safety and stability of the electric vehicle driving when it is applied to the electric vehicle.
