Abstract: In order to realize lightweight design of aluminum wheels, this article adopts topology optimization concepts as theoretical basis, combines finite element analysis technique, has done the lightweight research in the light of the specific aluminum wheels’ model. This article sets up the finite element models respectively with the spoke and Hub-centric parts as design variables, and optimizes spoke parts and Hub-centric parts using topology optimization, also redesigns the model and verifies the performance according to the topological optimum results. Research shows that the new model’s weight reduced 10% compared with the former model, material property further got effective application and realizes the lightweight design of automobile wheel.
