Abstract

A trunnion suspension system is usually adopted for a heavy-duty truck of the 6×2 or 6×4 drive system. A rear axle fixed to this suspension system takes vertical load and axial load of very complicated stress. Stress is created on the rear cover fixed area, resulting in fatigue. This paper deals with the optimum design of the rear axle case (rear cover fixed area) using the 3-factor & 3-level structure analysis of the finite-element method based on the comparison of experimental results with stress values obtained by the finite-element method
