Problems solved by technology

The advantage of these test facilities is that the scale of the tunnel is similar to that in the actual combat environment, and can reflect the explosive effect of explosives under actual combat conditions. The disadvantages are that the test preparation process and test process are complicated, the test time is long, and the manpower and material resources are large, which affects the temperature and pressure.

Abstract

The invention discloses a device for testing explosion and propagation characteristics of explosives. The device comprises a front end cover, a tank body, a double-headed stud, a sensor, a sensor mounting seat, a liner, a rear end cover, a positioning nut, a flange ring, a stud, a pressure transfer tube and a pressure transfer tube cover. According to the technical characteristics, an explosion tank and a pressure transfer pipeline are arranged in the device, the sensor is assembled in the wall surface, and shock-wave pressure data and heat effect data at each position point can be acquired; and moreover, according to the organic glass front end cover, the fireball change data in the thermobaric explosion process can be acquired. The tunnel and warship cabin interior explosion environment used by thermobaric explosives is simulated, and experimental study conditions of the explosion and propagation characteristics of the thermobaric explosives in a closed environment are met. The device disclosed by the invention is convenient to use, low in cost and suitable to be used in a laboratory environment.

Description

technical field [0001] The invention belongs to the field of explosives, and in particular relates to an explosion test device, in particular to an explosive explosion and propagation characteristic test device. Background technique [0002] Compared with high explosives, thermobaric explosives have the characteristics of long duration of shock wave positive pressure, large impulse, and long duration of fireball. When propagating in the air, the shock wave pulse decays slowly and travels far, especially in tunnel working conditions. When used under the environment, due to the long-distance propagation of the shock wave, it has a larger killing range for soft targets such as personnel targets and electronic equipment. Therefore, in the development and application of thermobaric explosives, it is necessary to measure and evaluate the explosion and propagation characteristics of thermobaric explosives, which has become one of the important research contents in the research and ...
