Abstract
A finite element model of a pure electric vehicle body was built. Based on the finite element method (FEM), static analyses under 2 common conditions, bending and torsion, were conducted. Meanwhile, free modal performance of the vehicle body was analyzed. According to the analysis results, the body structure features were evaluated and a structural optimization was in need. With the theory of relative sensitivity, 3 schemes for selecting size optimization parts were proposed. By a mixed sorting of all the relative sensitivity data, a final scheme was made and an optimal solution of vehicle body size optimization was achieved.
