High structural strength is an important performance requirement for an automotive steel road wheel. The induced stress of the wheel in the rotating bending fatigue test or rotating radial loading fatigue test was simulated by using the three-dimensional Finite Element Method (FEM). The deflection mode, stress distribution and stress amplitude of the wheel were evaluated. The calculated results were compared with stresses measured by strain gage. The comparison showed that the agreement of the calculated results and measured results was fairly good. Moreover, the effect of design parameters such as disc thickness, disc hat radius and rim thickness on the stress amplitude was numerically studied. Consequently, it became clear that the present FEM stress evaluating technique is a useful and effective tool for developing a new design wheel with high performance.
