Al6060S-T6의 크래쉬 박스 적용성에 관한 연구

Abstract

This study examined the possibility of replacing Al6082S-T6 with high rigidity with Al6060S-T6 with relatively low rigidity. Tensile properties were evaluated by making a tensile specimen in a crash box. The compression test was evaluated with a crash box, and the compression and crash tests were evaluated with a bumper beam assembled with a crash box. The characteristics of the compression test of the Al6082S-T6 crash box, the compression test and collision test of the bumper beam with the crash box were higher than those of the Al6060S-T6, but the impact energy absorption efficiency was low. It is judged that the damage range of the Al6060S-T6 crash box is smaller than that of the Al6082S-T6, and the collision performance is superior.
