A finite element model of an electric bus frame is built, the bending stiffness and torsional stiffness are calculated of the body structure; then the sensitivities of bending stiffness, torsional stiffness and mass about the thickness of components are analyzed respectively. Based on the sensitivity analysis results, through optimizing the thickness of the body components, the bending stiffness and torsional stiffness are improved while the mass of the body don't increase.
