Gear Faults Analysis Using Finite Element Method

In this study, gear faults analysis has been conducted by Finite Element Method (FEM) using ANSYS Software. It was conducted in order to investigate how failure modes in gears affect the gear mechanism. There are many failure modes in gear namely tooth crack, pitting, wear and scuffing. These modes affect gear mechanism in various ways and if not detected in early stage they may lead to a total system failure. The examples of system failure are high vibration state, loud noise, less power transmitted and fracture of teeth. In this study, the author will investigate how each failure modes will affect the frequency response of the system. At the end of the study, the difference of amplitude (deformation of a single tooth) between failure modes was determined to reveal the most risky fault
