The design of vehicle twist beam rear axle based on structure topology optimization

摘要

The structure optimization design of vehicle twist beam rear axle was conducted in this paper on the basis of topology optimization and HyperWorks software. The perfect material topology was found through optimizing defined designing space and the accuracy of optimization results was tested through K&C performance analysis so that rear axles with lighter weight but better performance can be designed. In this way, the direct design of products can be realized. Therefore, this paper will have great significance and guidance on the tightweight design of other vehicle parts.
