Abstract

This study aims to select optimum
materials for particular spur gear designs. An advanced material selection technique
called Ashby’s method was used to determine suitable materials according to
their material index. The method requires objective function, constraint and
free variables. Objective function was set to minimizing mass based on the
bending strength whereas the bending fatigue failure criteria is the
constraint. All the input parameters and modification factors during the design
process were taken as free variables. The suitable materials were ranked
according to their index value then subjected to gear designs. A number of gear
designs were performed with different types of materials to show the
differences between weights of the parts. Module and face width results were
also compared between each other. Lightweight and high strength materials
suitable for spur gear designs were found out. And up to 63% weight reduction
was achieved compared to conventional gear materials.
