Lightweighting of new energy vehicles is a core approach to improve cruising range and reduce battery costs. As a key load-bearing component, the structural optimization of wheel hubs is crucial to the overall vehicle performance. This paper takes the wheel hub of a new energy car as the research object, combining the streamlined structure of bird wings and the characteristics of lightweight bones to design a five-spoke rotating lightweight wheel hub. 6061-T6 aluminum alloy is used as a lightweight material. A 3D model is established through Creo. Static, modal, bending fatigue and radial fatigue analyses are carried out using ANSYS Workbench. The results show that the mass of the lightweight wheel hub is reduced from 13.2kg to 9.38kg, with a weight reduction rate of 28%. Moreover, the simulation results show that the maximum stress, deformation and fatigue life all meet the design standards, achieving a balance between strength and lightweighting. This provides theoretical and technical references for the research on lightweighting of new energy vehicle wheel hubs.
