Abstract
This paper studies the fatigue life modeling of key parts of armored vehicle suspension system. The life modeling was carried out for the surface crack initiation and expansion of the torsion shaft, and the mathematical model of fatigue crack growth life was established based on Paris formula, and the numerical calculation and simulation under different torsion stresses were completed. The two-stage mathematical model can provide theoretical support for the life analysis of the torsion shaft.
