Abstract
CAE technology has been applied for the crash safety design of vehicles, however, the optimum design has not been completed for the crash behavior of the vehicles. The authors have proposed a Statistical Design Support System (SDSS), and brought forward that the SDSS is one of the available optimal approaches for the nonlinear and dynamic phenomena. In this study, the SDSS was applied for the multi-objective optimization design of the reinforced members of a vehicle, where the weight, cabin deformation, and collision acceleration were chosen as the objective functions, and the simultaneous optimization for the functions was carried out. It was shown that the SDSS could be used as a practical multi-objective optimization tool for the crash safety design of vehicles.
