Topology Optimization of a Parallel Hybrid Electric Vehicle Body in White
Topology optimization design of a parallel hybrid electric vehicle (HEV) body in white (BIW) by applying Solid Isotropic Microstructure with Penalization (SIMP) method is presented. The BIW optimization of HEV takes into account not only the static loads, but also the loads of HEV in turning and braking conditions. Torsion playing a leading role in vehicle turning process and bending playing a leading role in vehicle braking process are converted to related vertical force imposed on the optimal model. The optimal result shows clear skeleton body in white of parallel HEV when volumetric constraint is 25％. Beam appears in the top of optimal automotive body in white when volumetric constraint is 40％. There is no significant change except increased thickness for the basis body in white of parallel HEV when volumetric constraints continue to enlarge.
