Abstract

The invention discloses a method and device for researching the quick reaction mechanism of an energetic material. The method is characterized in that the device for researching the quick reaction mechanism of the energetic material is adopted. The method comprises the following steps: positioning a monochromator in the position of a primary product characteristic spectral line, and recording the intensity time history (namely, time history curve) of the characteristic spectral line through a digital oscilloscope after photoelectric conversion, so as to study the time history of chief constituents of the energetic material decomposed due to impact; simulating the dynamic characteristic curve of the quick reaction of the energetic material with a reaction power calculation program, and correcting the reaction passage of the quick reaction of the energetic material according to the experiment detected occurrence time, inflection point time and maximum peak time of the primary product. A simplified reaction model obtained according to the method focuses on a main path, abandons reaction with poor impact, and can accurately reflect the real processes of the quick reaction of the energetic material under practical experimental conditions.

Description

Technical field [0001] The various embodiments of the present invention relate to the field of spectroscopy measurement technology, and more specifically to methods and devices for studying the rapid reaction mechanism of energetic materials. Background technique [0002] Energetic materials are a class of materials that have high energy performance and can release a large amount of energy. They are widely used in aerospace, military industry and other high-tech fields. Therefore, the research on the reaction mechanism of energetic materials has always been a hot spot. To study the reaction mechanism of substances, it is necessary to analyze the chemical kinetics and decomposition channels in the reaction process, which is mainly based on the transient real-time measurement of intermediate products. In this regard, various spectroscopic analysis techniques can be used as a means to detect the atomic and molecular level of energetic materials, which is conducive to a more comprehe...
