一种温压内爆炸准静态压力测量方法研究
Test Method Research for the Quas-Static Pressure on Inside-Explosive
摘要
Abstract
Aiming at accurate quasi-static pressure measurement for thermobaric explosion of confined space,a kind of quasi-static pressure measurement component were designed according to the filtering effect characteristic of pressure transmission pipeline. The measurement method of quasi-stat pressure for thermobaric internal explo⁃sion were established. The quasi-static pressure measurement component were constituted by piezo-resistive pres⁃sure sensors and micro transmission pipeline which were formed by spiral concave structure on the cylindrical bar and the tube wall. By using it,the spread of high frequency shock wave component of explosive pressure wave can be restrained and the influence to pressure sensor capability of explosive light and heat can be decreased. The fre⁃quency response characteristic of pressure measurement component and measurement error were measured respec⁃tively by using shock tube device and quasi-static pressure device. The pressure rise time was less than 0.24 ms and pressure measurement error was less than 0.6%. It can meet the needs of quasi-static pressure measurement in inter⁃nal explosion field. At present,the measurement method has been applied to thermobaric internal explosion experi⁃ments and provide measurement foundation to assess the explosion energy of thermobaric explosive.关键词
