Abstract

In this study, we investigated the capacitive effect and the electromagnetic coupling on the measurement chain induced by impact experiments with a gas gun or powder gun. Reduced bandwidth and noise were noticed on experimental signals. Rogowski coil measurements were added on the cables to characterize the electromagnetic coupling. The perturbation currents on the cables were quantified depending on the configuration. The gauge, the transmission line and the conditioning system were modeled. The calculations reproduced the electrical wave arrival time, the transmission line transfer impedance and the conditioning system transfer impedance; and the bandwidth limitation has been displayed. A capacitive effect with the piezoresistive manganin gauge embedded into the sample was identified, depending on the experimental setup.

摘要

在本研究中，我们研究了气枪或火药枪冲击实验在测量链上引起的电容效应和电磁耦合。实验信号出现了带宽降低和噪声。在电缆上增加了罗戈夫斯基线圈测量，以表征电磁耦合。电缆上的扰动电流根据配置进行了量化。对标距、传输线和调节系统进行了建模。计算再现了电波到达时间、传输线传输阻抗和调节系统传输阻抗；并且显示了带宽限制。根据实验装置，识别出了嵌入样品中的压阻式锰铜应变片的电容效应。
