Analysis and Optimization for Cracking of a Steering Tie Rod based on Arc Length Algorithm

An investigation was performed on steering tie rod for cracking with strength and buckling analysis theory, which showed a low risk of failure. In order to solve this problem, a “necking down” method was used to optimize the length and location by Arc Length Algorithm, which was proved by pressing and impact test. It is shown that simulation results are in consistency with tests, “necking down” can alleviate cracking and improve quality efficiently on the premise of mere decrease in pressure resistance.
