Abstract

The main purpose of an engine mounting components is to support the powertrain system in an automobile which subject to thermal loading. This study examines a methodology to predict the fatigue life of an engine mounting component using ANSYS software. An engine mounting component is modeled using CATIA software and FE analysis is carried out using ANSYS software. The critical condition caused by the cyclic load and thermal loading may lead to component failure. The scope of the study is to analyze the design, optimize and compare between the two types of engine mounting component under cyclic stresses and thermal loading. The stress concentration factors were estimated based on the structural analysis. The structural analysis is performed on specified part for a given load and support conditions. In order to use a finite element analysis it is necessary to know the mechanical properties of the material. The tensile test, Rockwell hardness test and thermal inspection were conducted in this study to determine the mechanical properties and thermal behavior of an engine mounting component. The simulation of fatigue analysis by finite element software on the existing PROTON SAGA and PERODUA KANCIL engine mounting component to determine the maximum stress and fatigue life on the model due to the effect of thermal loading and cyclic stresses. The final simulation results obtained in this study shows that the higher thermal loading will cause a lower fatigue resistance or shorter life of an engine mounting component.
