Mode Controlling Approach on Multi Level Optimization for Crash Safety design of Vehicle 2001-01-3111

It is important to improve the deceleration characteristic and the cabin deformation for a collision safety design of vehicle. At the same time it is required to reduce the vehicle weight to satisfy the driving performance and environmental restriction. Therefore there is a strong demand to develop an optimization approach to design a safer and lighter vehicle. 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, they proposed a new concept called as mode controlling approach to keep the side members in ideal buckling mode. As a result, it was shown that high deceleration performance and light body can be realized by using this approach and SDSS.
