In order to improve the vehicle chassis structure durability, the fatigue analysis and optimization design of the low control arm (LCA) was taken. A finite element model was established. By using this model, the stress distribution and lowest point of lifetime of the control arm under fatigue load was calculated. Based on the results of analysis, the optimization scheme according to the structure characteristics of components was presented, and a solution to improve the control arm fatigue life was given out. The research provided reference for engineering application of calculation and optimization of chassis components fatigue life.
