Stress and Crack Simulation on Axle Housing Mitsubishi L300 Pickup Car using Finite Element Method

Abstract

Axle housing in pickup cars receives the main load that is direct or indirect. The direct load referred to is the weight of the load and the weight of the vehicle itself, while indirect loading can be in the form of twisting and bending moments. Due to the load experienced by the axle housing will result in deformation, cracking, and even fractured. Based on the case of failure, an analysis of the axle housing was performed which covers two things, namely stress analysis and crack analysis. Axle housing analysis uses the Finite Element Method (FEM) approach, through the Ansys software. The result of stress analysis shows the maximum value of Equivalent (von-mises) Stress is 14,356 MPa, the Maximum Principal Stress is 14,977 Mpa, and the Maximum Shear Stress value is 7,5471 MPa. The result of crack analysis shows the maximum value of J-Integral is 0.00051126 mJ / mm2 and the maximum value of SIFS (K1) is 10.823 MPa.mm0.5.
