Embodiment 1

[0037] refer to Figure 1 to Figure 4 , the non-ideal explosive explosion performance measurement device in this embodiment includes an explosion chamber 1, an explosion rupture disc 2, a projectile 3, a projectile sliding cylinder 4, and a speedometer 6 (the speedometer is a standard laser speed measuring probe that can be purchased) and sealing ring 5.

[0038] see figure 2 , The explosion chamber 1 is a horizontal cylinder, and the specific structure includes a sealing end cover 11 and an explosion chamber body 12, on which are installed an initiating electrode 13, a hanging charge ring 14, a sealing gasket 15, a pressure gauge 16 and a vent valve body 17.

[0039] The sealing end cover 11 and the explosion chamber 12 are connected by threads, and the gas sealing is carried out by a sealing gasket 15 in the middle.

[0040] The sealing end cover 11 is in the shape of a truncated cone, which is integrally processed by high-strength stainless steel. 1, along a circle with...

Embodiment 2

[0058] This embodiment gives an example of measuring the detonation performance of a non-ideal explosive containing aluminum using the device for measuring the detonation performance of a non-ideal explosive in Example 1.

[0059] The formula of the aluminum-containing non-ideal explosive used in this example is 65RDX / 30Al / 5 viscosity, and a cylindrical explosive column with a diameter of 40 mm and a height of 45 mm is prepared by a compression molding process.

[0060] Put the explosive diaphragm 2 flatly into the circular counterbore at the right end of the explosion chamber 1; put the projectile 3 into the projectile sliding cylinder 4, and the projectile support 31 is flush with the outer end surface of the flange 41, and in the explosion chamber 1 Place the sealing ring 5 between the projectile sliding cylinder 4, pass through the through holes on the flange 41 and the sealing ring 5 successively with bolts, and screw into the threaded hole on the right end surface of the ...

Abstract

The invention discloses a nonideal explosive work capacity measuring device. The device comprises a priming electrode, an explosion cavity, a bullet sliding cylinder, bullets and a velometer, wherein the inner top of the explosion cavity is provided with an explosive suspension loop; the priming electrode is internally communicated with the explosion cavity; the explosion cavity is connected with the bullet sliding cylinder and the explosion cavity and the bullet sliding cylinder are communicated; the bullets are arranged in the bullet sliding cylinder; and the velometer is arranged in the bullet sliding cylinder. According to the measuring device, the bullets and the bullet sliding cylinder are designed, and the bullet sliding cylinder is communicated with the explosion cavity, so that explosion impact shock wave energy, product expansion energy and energy released by sustained reaction are converted into kinetic energy for accelerated motion of the bullets in the bullet sliding cylinder, the velocity of the bullets flying out of an opening of the bullet sliding cylinder is measured by utilizing the velometer arranged at the tail end of the bullet sliding cylinder, and the flight kinetic energy of the ruler bullets can be calculated; according to the principle of energy transformation and conservation, the kinetic energy of the bullets is the work load of an explosive, namely the explosive work capacity.

Description

technical field [0001] The invention relates to a device for measuring the explosive work capacity of explosives, in particular to a device for measuring the explosive work of non-ideal explosives. Background technique [0002] In order to improve the overall working ability of explosive explosion, the most important technical approach is to add metal fuel and oxidant with high combustion calorific value to high explosive to form high-energy mixed explosive, which has obvious non-ideal detonation Characteristics, the critical diameter of the detonation is larger, the release time of the explosive reaction energy is longer, the expansion of the product is slower, and the ability of the explosion to continue to work is stronger. [0003] At present, there are mainly two kinds of test devices for evaluating the blasting ability of explosives: reaming lead casting and ballistic mortar. [0004] Reaming lead casting is to place explosives in the central inner hole of a cylindric...
