本文描述在材料中测量冲击波压力剖面的实验技术。实验中采用压装炸药平面波发生器、衰减器、飞板、靶板和压装炸药平面波发生器、靶板两种爆炸系统。采用两种结构形式的电阻值分别为10欧和50欧的刻蚀锰铜箔压阻传感器,同时用同轴探针监测试件中的冲击波速度和粒子速度,标定压力峰值。本文着重讨论了传感器供电系统,信号传输记录和数据处理中要注意的事项等有关问题,并给出了在实验中测得的冲击波压力剖面的示波记录。
This article describes experimental techniques for measuring shock wave pressure profiles in materials. In the experiment, two kinds of explosive systems, such as press-mounted explosive plane wave generator, attenuator, flying plate, target plate and press-fitted explosive plane wave generator and target plate were adopted. Using two kinds of structural resistance of 10 ohms and 50 ohms etching manganese copper foil piezoresistive sensor, while using the coaxial probe to monitor the shock wave velocity and particle velocity in the specimen, calibration pressure peak. This article focuses on the power supply system of the sensor, signal transmission and data processing matters needing attention and other related issues, and gives the oscillometric record of the shock wave pressure profile measured in the experiment.
