| 摘 要： | 本文介绍了一种用于对1000MPa 以下的高压传感器进行动态特性标定的水激波管装置,装置内径30mm,管长550mm,用叠氮化铅点火头为爆源,用 PVF_2压电薄膜做成色散压杆传感器监测其压力波形。利用该装置对二种不同原理的高压传感器进行了动态标定试验,得到了初步的频率响应特性的试验结果。

| Abstract: | This paper describes a water shock tube for dynamiccalibration of high pressure tranducers up to 1000MPa.The apparatushas an inner diameter of 30mm and a length of 550mm.The lead azidedetonator is used as an explosive source.The pressure waves is monit-ored by a dispersive pressure bar gauge made with PVF2 piezoelectricfilm.Two different kinds of high pressure tranducer have been testedby this apparatus,and their dynamic responses characteristics areobtained. |
