Research and Application on Automotive Aluminum Bumper Based on Topology Optimization

Abstract:

Based on the explicit dynamic finite element analysis software, the use of hybrid cellular automata (HCA) as an optimization model, the collision of beams in the aluminum front structure optimization design. The 6061 aluminum alloy before the collision of beams to replace a model of the original steel beams, trolley collision simulation and experimental validation of the results show that the aluminum front impact beams than the original steel before the collision beam quality to reduce by 25% and has a higher flexural strength, low-speed collision, aluminum front impact beams than the original steel system energy absorption increased by 45.6%.
