Fracture Failure Analysis of Torsion Bar with Surface Defects
LI Li , ZHU You-li, HUANG Yuan-lin
(National Key Laboratory for Remanufacturing, Beijing 100072, China)
Abstract: Scanning electronic microscope (SEM) and X-ray energy dispersive analysis (EDX) were used to investigate fatigue
failure of the torsion bar with surface defects of a tracked vehicle, results show that the crack initiation at surface and
propagation of the crack were influenced by accumulated residue stress at the surface and sub-surface. The reasons of life
decline of torsion bar with defect were analyzed and some advices were given to the process of manufacture and maintenance.
Key words: torsion bar; fatigue; fracture; failure; service life
