The Deformation Characteristics of Hydro-Forming of Differential Gear Box for Automobile

Abstract:

The hydroforming process of differential gear box for automobile under axial compressive load and internal bulging pressure was simulated and the load paths were optimized. The hydroforming process is divided into two steps. The deformation under different load paths was investigated using dynamic explicit finite element method. The distribution of equivalent strain and thickness was investigated as well. The simulation results show that the forming path for the first step is optimal when internal pressure changes linearly from 37MPa to 65MPa with the axial displacement.
