Abstract : A fully parameterized implicit 3D geometric model and, based on which, a parameterized FE model for the body-in-white (BIW) of a car are successively built with SFE-Concept software, and the low-order natural vibration characteristics and torsional and bending stiffness of the BIW are calculated with their validities verified by tests. A multi-objective lightweight optimization on the BIW is conducted by using genetic optimization algorithm with the thicknesses of 66 BIW panels selected by relative sensibility analysis as lightweight design variables, the total mass and torsional and bending s
