FINITE ELEMENT ANALYSIS AND FATIGUE ANALYSIS OF SPUR GEAR UNDER RANDOM LOADING
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 4, Issue 6
Abstract
Every component or structure is designed based on factor of safety. Which means the component should not fail below the design load. But in actual arena it is not so. There is a need for an analysis which predicts the life of the component. This requirement is satisfied by Fatigue analysis. It takes all types of loads i.e., static loads, random loads varying with time and gives life of the component as output. Present analysis is one such analysis of carrying fatigue test on spur gear using software package ANSYS.The gear fitted in the gearbox of armored tracked vehicle is vulnerable to considerable fatigue damage over its life period due to the dynamic excitations caused by the terrain undulations, the rotating wheel and track assemblies. For this purpose, initially static analysis of the model was carried out to validate the model and the boundary conditions correctness. Further Modal analysis is carried out to determine the dynamic characteristics of the gear model. The present work deals with the calculation of static and dynamic analysis, and fatigue life estimation of test gear, which is contacting master gear and assuming loading on the gear is random or constant amplitude by Finite Element package ANSYS. Initially gear system is modeled in CATIA V5 later it is imported into ANSYS for further analysis.
