Study on lightweight of aluminum wheels for motorcycles
The weight of motorcycle wheels will affect both the handling performance and the cost.In order to design the wheel's structure and size reasonably,in this article,efforts are made to select the optimization objectives,design constraints and those manufacturing constraints by means of topology optimization,so as to identify the best distribution of materials,while ensu-ring that the wheel has good stiffness and strength on one hand and there is a load-transfer path suitable for the structure on the other hand.Based on the results of topology optimization,the related dimensions of the wheel are parameterized and the paramet-ric model is set up.Finally,the optimization process of the wheel is built in the parametric optimization software for automatic op-timization.It is shown that the wheel's weight after parametric optimization reduces by 13.3％.Both the efficiency and the accu-racy in the wheel's weight reduction have greatly improved with the help of such technologies as topology optimization and para-metric optimization.
