Fatigue Failure Analysis and Improvement of Automotive Steering Link Mandrel Based on ABAQUS
The steering tie rod is an important part of the steering mechanism of the automobile,which plays a role in transmitting movement in the steering system,and directly affects the stability of the vehicle handling,the safety of the operation and the service life of the tire.In this paper,ABAQUS is used to conduct CAE analysis on the outer ball joint mandril of a steering tie rod of a certain vehicle model and the S-N curve of its material is combined to verify the irrtionality of the product designed according to experience for the first time.Then,the product meeting the fatigue life requirements of customers is designed by CAE finite element analysis method and verified by experiment.
