Abstract: Based on the Pam-Crash/Safe software, the basic vehicle-dummy finite element model for 25% overlap frontal collision was built. The bending and compression performance expressions of the main energy-absorbing components were simplified. With the restraint of structural intrusion, the total target energy absorption was assigned to the sub-components. Then, the average reactive forces of the sub-components were calculated according to the crush length. Finally, the parameters of cross-sections were designed to satisfy the average reactive forces and energy-absorbing requirements. The results show that the designed frontal structure can satisfy the regulation requirements of the three frontal collision conditions, which include 20% overlap frontal collision. This method not only improves the efficiency of structural optimization, but also realizes "forward design" to a certain degree.

Key words: vehicle engineering, frontal collision, design of frontal structure, energy-absorbing, equivalent simplified model
