Abstract

The invention relates to an explosive performance testing device, in particular to an explosive friction sensitivity tester, which solves the problems of the prior art such as low automation degree, low test accuracy, difficulty in ensuring test condition and complex operation. The explosive friction sensitivity tester comprises a box body, a belt clip support fixed on the inner wall on one side in the box body, a friction belt chip inserted on the belt clip support, an impact cylinder fixed on the upper wall of the box body above the friction belt clip, a sample support base with a rotation hole and fixed on one side of the belt chip support, a support base inserted in the rotation hole on the sample support base for accommodating explosive, an explosive support tube inserted in the hole of the support base, and a top bar penetrating through the explosive support tube, wherein one end of the top bar corresponds to the friction belt clip and the other end of the top bar is butted against with a pre-tightening cylinder fixed on the sidewall of the box body. The invention has the characteristics of preciseness, feasibility, applicability, convenience, safety, etc. The invention can test the safety and the reliability of explosives, and has wide application range.

Description

technical field [0001] The invention relates to an explosive performance detection device, in particular to an explosive friction sensitivity meter. Background technique [0002] Since the outbreak of the First World War, the war has greatly increased the demand for explosives in countries around the world. At the same time, the demand for explosives in the civilian industry has also continued to increase. Explosives will inevitably bring some accidents from production to use. Many scientists have begun to pay attention to the stability and sensitivity of explosives. The friction sensitivity test is one of the eight stability tests of pyrotechnics, and it has high requirements on the instruments used. The friction sensitivity meter is an instrument for measuring the friction sensitivity of propellant and explosives through certain parameters, and conducting related friction sensitivity tests. [0003] In recent years, the application of high technology in weapon systems ha...
