Explosive Temperature Field Test of the Thermobaric Bomb Based on the Infrared Thermal Imager
摘要
Abstract
The complex field environment has greatly affected the measurement accuracy of the explosion temperature field by the infrared thermal imager. In this paper, the factors affecting the precision of temperature measurement are analyzed from the theoretical point of view, and the relevant improving measures are put forward. In the thermobaric bomb explosion test field, the infrared thermal imager is calibrated by field standard black body. The explosion processes of the temperature and pressure bomb are collected accurately and the relevant data are extracted. The experimental data is processed via MATLAB, and then the temperature field distribution of the explosion fireball surface is obtained: the maximum temperature of the explosion fireball surface is 2881℃;the temperature field duration is 1300ms at 1000℃ and above; the maximum distribution range of the temperature filed is12.61m at 1000℃ and above. Moreover, the CCD high speed camera is set up to carry out the visible light band. The results show that the test data have high accuracy and reliability.关键词
