摘要

    摘要
  • 摘要: 针对飞行破片动能测试，提出了一种采用光幕测试飞行破片动能的方法。该方法采用两台光幕靶测试飞过光幕的破片的速度，通过破片穿过光幕输出的波形提取体积信息，得到破片的穿靶质量，进而得到破片的动能。文中分析了光幕输出波形与破片体积关系的理论模型，采用3种典型的旋转对称形状物体仿真验证了理论模型，并研究了一种标定方法。实弹射击试验表明，所提方法可以测量旋转对称破片或弹丸的动能，测量精度满足靶场测试的要求。
    Abstract: Aiming at the measurement of kinetic energy for flying fragments, a measuring method of kinetic energy for the flying fragment using single screen was presented. Two screens were used to measure the speed of the flying fragment in the method, the volume information was got by mean of the output waveform of the fragment passing through the screen, further the quality and the kinetic energy of the fragment were obtained. This paper analyzed a theoretical model of the relationship between the output waveform of the screen and the volume of the fragment. Three typical rotational symmetry objects simulations were used to verify the theoretical model, and a calibrating method was studied. The testing result of the ball firing proved that the proposed method could measure the kinetic energy of the rotational symmetry projectile or fragment, the measurement precision satisfied the requirement of the range test.
