Optimization of a Wheel Rim for Reduction of mass and 1st mode frequency maximization with modeFRONTIER

Bodur Mehmet Ata - FIGES (Turkey)

Abstract

Wheel rim is an important part of a vehicle, which directly affects the safety, performance, noise level and style of it. Here, weight reduction and the 1st mode free vibration frequency characteristics are investigated for a wheel rim, which poses the problem as multi-objective. The frequency is also constrained to be higher than 320 Hz. Geometric model is parameterized in CATIA, and the problem is solved with the art of design FEM tool ANSYS Workbench, and the optimization tool modeFRONTIER. NSGA-II algorithm is used for the optimization task, which proved to be performing well in obtaining uniform distribution of design points on the Pareto set.
