The utilization of magnesium alloy wheels is useful for automobile lightweight. A kind of magnesium alloy wheel was designed by using TRIZ theory, and then the three-dimensional CAD model was created using UG NX 7.0. According to these, the static structural analysis of the magnesium alloy wheel had been simulated with finite-element method. It can be shown that the high stress distributes mainly in the region of bolt holes and the transitional region between the rim and spokes of the wheel. The maximum stress is less than the yield stress of magnesium alloy. Some valuable references are provided for the design and development of magnesium alloy wheel.
