The good Automobile front energy absorbing structure is an important part in automotive crash safety. The better performance of absorbing structure, the lighter damage of vehicles and other components, and the lower automotive collision repair cost.. In this paper, the motor vehicle energy-absorbing structure was completed by apply Finite Element (FE) method. This FE method was carried out apply the software LS-DYNA. Energy-absorbing structure of automobile usually made of thin wall metal tube. The tube was using of aluminum alloy and carbon steel material. Emphasis was focused upon discovery an optimum lateral section shape of the thin wall metal tube in order to enhance the crashworthiness. Some types of lateral section were compared and researched. Results show that the repair cost of the tube enhanced obviously when aluminum alloy lateral cross section was employed.
