Failure Analysis of Distributor Gear

Abstract

This study experimentally and theoretically investigated the fracture damage on the distributor gear of a front-wheel drive automobile. The experimental stud-ies initially analyzed the fracture surfaces of the gear in the scanning electron microscope (SEM). Subsequently, microstructure analysis and mechanical tests were performed. In the theoretical study, on the other hand, static analyses were performed using the finite element method on the ANSYS software program. Static analyses revealed equivalent stresses on the piece and determined its criti-cal regions. Finally, the theoretical and experimental studies were compared with literature data. As a result, the occurrence of a ductile fracture was observed and it was determined to be the area where the most critical fracture occurred.
