Abstract

As one of effective methods, topology optimization design has been extensively applied to improve structural performance and efficiency of material usage for lightweight automobile. The chassis structure is an important part of new energy vehicle structure that presents many design requirements including stiffness, strength, etc. However, finding an optimal layout of the chassis structure of a new energy vehicle remains fairly challenging through conventional design methods. This study proposed a variable density topology optimization method for this purpose. Based on variable density topology optimization design theory, a numerical computation is carried out to optimize the chassis structure of new energy vehicles. The results show that the optimal load transmission path and space structure are obtained under bending and torsion conditions, which may provide a reference for further detailed chassis structure design of new energy vehicles.
