Bending fatigue prediction accuracy of steel wheel can hardly be guaranteed without clearly understanding the influence of stamping process on fatigue. In this research, multi‐step stamping processes of spoke were analysed by different finite element simulation techniques. Major influences of stamping process on fatigue property were distinguished. Data‐mapping technique was used to transfer information between stamping and fatigue analysis models. Difference material experiments were carried out to research the influence of prestrain on material properties. Modified E‐N function was established according to the theoretical analysis and material experiment results. Bending fatigue finite element simulation was carried out, and result matched experiment well both in position and cycle life.
