Crash box is one of the most important automotive parts for crash energy absorption and is equipped at the front end
of the front side member. The specific characteristics of aluminum alloys offer the possibility to design cost-effective
lightweight structures with high stiffness and excellent crash energy absorption potential. This study deals with
crashworthiness of aluminum crash box for an auto-body with the various types of cross section. For aluminum alloys,
Al7003-T7 and Al7003-T5, the dynamic tensile test was carried out to apply for crash analysis at the range of strain from
0.003/sec to 200/sec. The crash analysis and the crash test were carried out for three cross sections of rectangle, hexagon
and octagon. The analysis results show that the octagon cross section shape with Al7003-T5 has higher crashworthiness
than other cross section shapes. The effect of rib shapes in the cross section is important factor in crash analysis. Finally,
new configuration of crash box with high crash energy absorption was suggested.
