Today, as the number of kinds of vehicles, ships and aircrafts becomes bigger and bigger, and the speed becomes faster and faster, the collision accidents are increasing every year, causing serious loss of life and property. Energy-absorbing device can absorb most of kinetic energy, reduce casualties and the property losses to the maximum. Therefore, it is significant that advanced research on the energy-absorbing device is to reduce casualties and economic losses.
In this paper, the vehicle is regarded...
