Abstract

In this article, the design of the 22.5 × 9.00 hot-stamped lightweight wheel was optimized based on finite element analysis of stiffness. To improve the bending and radial stiffness of the wheel, under the condition to meet the requirements of bending and radial loading stress, the finite element stiffness analysis was carried out on the following three optimizations: increasing the spoke’s thickness, modifying the shape and size of the windows, and setting up shuttle-shaped stiffeners between the windows. The numerical simulation results showed that the maximum bending stiffness around the bolt holes of the spoke increased by 1.4 × 106 N/m, and the maximum radial stiffness at the outer edge of the rim increased by (2.25–4.18) × 107 N/m, which met the product requirements for stiffness and stress and achieved the goal of wheel lightweighting.
