Research on Aluminum Structures for Crash Energy Absorption

Article of Honda R&D Technical Review Vol.13 No.2

Summary

This research describes aluminum crash boxes for the purpose of absorbing crash energy. In this research, the load conditions of the boxes were calculated and the mechanisms of energy absorption were analyzed by experiment. This analysis achieved a crash box with a highly effective section shape. The research also achieved the additional goal of increasing the accuracy of crash simulation for evaluation of energy absorption by this crash box.
