The numerical model of the intake and exhaust rocker was established by the finite element method. The stress and deformation distribution were gained on three different materials of the rocker arm. On this basis, the improved design idea of the rocker was obtained through the topology optimiza?tion, and the model of this new rocker made of aluminum alloy was restructured. The higher stress and deformation level were reduced through the finite element analysis method.
