摘要

Auto-body’s front end structure, such as bumper and crash box, has the vital function of protecting other components from damage during low-velocity collision; moreover, it should accomplish excellent lightweight effect under the insurance of crashworthiness. This article combined the two approaches of lightweight improvement that listed as using structural optimization and replacing original materials with high strength and high mass efficiency materials or employing reinforced materials to conduct the crashworthiness optimization of assembly of bumper, crash box, and front rail. The original materials of bumper, crash box, and front rail were replaced by aluminum alloy 6060, TRIP800, and DP800, respectively. Aluminum foam was filled in bumper to replace the original reinforced plate and also was filled in crash box to increase energy absorption. The comparisons were made between an optimal selection from the multiple materials designs and the single material design. During optimization, crashworthiness ...
