The tire bead, as the most important load-bearing component at bead area, is closely related to durability of tire, but its structure developing slowly. For this reason, topological whole design was proposed, although it performs well, many defects existed due based on traditional experience. Therefore, paper studies topology shape optimization algorithm, delves into main criterion von Mises an...
