摘要
气炮是广泛用于研究物体撞击速度与破坏效应的一种动力学实验装置。针对传统测量气炮中弹体飞行速度方法存在的问题,提出新型激光测速方案。通过测量弹体遮挡不同测点激光束的时刻,计算弹体的飞行速度。根据该方案设计的测量系统做了仿真分析和标定实验,证明设计方案正确可行。目前,已研制成功并已应用于实际测量,极大地提高了测量的效率和准确度。
Air- gun is a dynamical experimental equipment that is widely used to study the velocity of object and damage and destructive effects. A new system is proposed to measure the body＇s velocity in air - gun based on laser technique. The principle and constitution of the system are introduced in detail. Parts of the simulation and experiments are presented. The system has been applied successfully, the efficiency and accuracy of measurement are improved.
