摘要

为确保汽车碰撞过程平稳性，提高吸能装置的自动化程度，针对螺纹剪切式汽车碰撞吸能装置，为其增加新的保险杠系统，并采用以单片机为核心的控制系统，通过接收传感器获取的轮速信号，计算碰撞能量大小，据此即可调整吸能装置的吸能能力。这样吸能装置可以在不同速度下具有相应的吸能能力，即实现吸能能力的自动控制。

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.
