| Abstract: | Base on the Ls-Dyna and Altair Hyperstudy, the size and shape of crash box have been optimized to achieve the maximal internal energy, when the thickness and shape of crash box set to design variables, and the mass and rigid wall force set to constraints. The lastest result after optimization shows that the internal energy of the crash box increased 10%, while the mass and rigid wall force hold the line. |
