Analysis of Knuckle Arm's Fatigue Life

Abstract:

Article Preview

The transition fillet radius and surface roughness have a great influence on the part’s fatigue life. In this paper, we analyzed the reasons of a light vehicle’s knuckle arm fracture theoretically by finite element method and took corrective measures such as enlarging the transition fillet and improving the surface quality. After simulation test, we learned that these measures enhance the fatigue life of knuckle arm indeed.
