Abstract

For insuring the automobile collision process steady, and improving the degree of automation of energy-absorbing equipment, the energy-absorbing equipment added a new bumper system by cutting the screw thread teeth for automobile collision are aimed at, the control system with a microcontroller core is used, the collision energy can be calculated by the wheel-velocity from the sensors, according to the collision energy, the required energy-absorbing capability of energy-absorbing equipment can be adjusted. Thus, the energy-absorbing equipment will have different energy-absorbing capability for different vehicle speed, it is realized that the energy-absorbing capability can be controlled automatically.

Key words
