A procedure for impact strength estimation of the automotive wheel has been developed based on static FEM analysis and simplified dynamic analysis using a mass-spring system. Aluminum disk wheels were analyzed, and the critical drop height for failure was estimated. The effects of two factors, (1) the moment of inertia of the spokes and (2) the thickness of the rim flange, on the impact strength of the wheel were investigated. The analytical results show good agreement with results of the impact test of the forged aluminum disk wheel. In addition, impact tests of cast aluminum disk wheel were performed. In thiis case, the failure at the compressive side of the sporke was observed. The mechanism of this type of failure was discussed based on the results strain measurement.
