Fatigue Analysis of Front Axle Using Finite Element Analysis

This study article provides a complete investigation of fatigue conducted on the front axle of a heavy-duty truck under applied forces, utilising Ansys simulation software. The objective of this study is to evaluate the structural integrity, endurance, and potential points of fatigue failure of the front axle when subjected to stress circumstances representative of real-world scenarios. The approach employed in this study encompassed the development of a comprehensive three-dimensional (3D) model of the front axle. This model incorporated pertinent material properties and applied forces that are representative of typical trucking operations. The utilisation of finite element analysis (FEA) methodologies was employed in order to model the response of the axle to the applied forces and evaluate its fatigue characteristics. By means of meticulous examination, essential variables were assessed, including safety aspects, ultimate lifespan, and cumulative damage. The analysis of the safety factor demonstrated a significant margin of safety, as indicated by a maximum safety factor of 10, indicating a high level of reliability under the given loading conditions. Nevertheless, it is worth noting that certain localities exhibit lower safety factors, specifically the lowest value of 2.681. This observation draws attention to the possibility of fatigue vulnerability in these particular areas.
