Problems solved by technology

[0004] As the formula design of a large number of non-ideal explosives has shifted from thermodynamics to kinetics, the evaluation of simple workability can no longer characterize the energy output structure of explosives, nor can it guide the formulation kinetics design. A non-ideal explosive work power characterization system for the relationship between force and detonation reaction process, thus revealing the kinetic process of explosive detonation reaction

Abstract

The invention provides a non-ideal explosive detonation power capability and power measuring device. The device mainly comprises a detonation cavity end cap, a detonation cavity, a nylon sleeve, an impact end cap, a piston rod, a connecting rod, a hydraulic damper, a base and a ceramic shell. A closed cavity design is adopted, all mechanical work done by diffusion of a non-ideal explosive detonation product is measured, explosive detonation instant work power is measured by recording displacement parameters and damping force parameters of a hydraulic damper, and the problem that an existing open type measuring device is incomplete in decompression and work measurement, cannot measure power and the like is solved.

Description

technical field [0001] The invention belongs to the technical field of explosion performance evaluation of propellant and explosives, and relates to a non-ideal explosive explosive work ability and power measuring device. Background technique [0002] Non-ideal explosives are a type of explosives with large critical diameter and wide detonation reaction zone. The detonation heat is the maximum potential for external work. However, according to the law of thermodynamics, all heat cannot be converted into work, so the accuracy of non-ideal explosives’ work ability Measurements have high practical value. [0003] At present, many evaluation methods of explosive explosion work have been established, such as lead casting method, ballistic mortar method and so on. The lead casting method was identified as the international standard method for determining the work of explosives at the Fifth International Conference on Applied Chemistry in 1903. The method has the advantages of sim...
