【摘要】 比冲量测量是脉冲辐射和爆炸与冲击实验研究中非常重要的参数测试技术。对靶托-传信杆冲量传感器的测速方式进行改进,采用光子多普勒测速仪对传信杆自由面进行连续速度测量。对一定面密度的光敏炸药在脉冲光源起爆下产生的比冲量进行了测量。实验数据表明,该冲量传感器能够较全面地反映靶托-传信杆组件在爆炸冲量作用下的运动过程。最后指出了该传感器存在的问题和进一步改进的措施。更多还原

【Abstract】 Impulse measurement is an important technique in the experimental research of impulse radiation,explosion and shock. The method of velocity measurement in the target holder-bar impulse sensor is improved with photonic Doppler velocimetry which measures the velocity of the bar’s free surface. The impulse is measured in the explosive experiments of light-initiated explosive with a known area density.The results show that the impulse sensor exhibits the whole movement of the plate-bar subassembly under explosion. The problems and improvements of the impulse sensor are pointed out.更多还原
