光纤布喇格光栅的炸药熔铸温度监测研究
Research of Temperature Monitoring for Process of Melt-cast Explosives based on Fiber Bragg Grating
摘要
Abstract
In order to realize temperature monitoring effectively , a multiple channels data demodulator has been used to detect the temperatures in melt-casting process of explosive , as well as a grating sensor with special package .It intro-duced the principle of grating sensing , fiber Bragg grating data demodulator and the packaging process of fiber Bragg grat -ing.The obtained temperature data were processed by Metlab and Origin to draw a temperature -time curves.It is most valu-able to obtain temperature curves during the process of melt-cast explosive especially at the moment when the phase transfor-mation occurred .The results show that the explosive can release latent heat in the process of melt-casting, and the tempera-ture of explosive rises from 88℃to 90 ℃.The experimental results prove that special packaged fiber Bragg grating sensor can be used well for temperature measurement in explosives melt-casting process .关键词
