An Indoor Soil Explosion Dust Test System

Abstract

The invention discloses an indoor soil explosion dust test system, which belongs to the technical field of explosion testing. The system includes an explosion hole, an explosion subsystem, a flash X-ray subsystem, a high-speed camera subsystem, a laser transmission characteristic test subsystem and a trigger device. The explosion hole has a double-layer structure inside and outside; the explosion subsystem is set in the inner layer of the explosion hole to generate soil explosion dust; the flash X-ray subsystem can capture the dust image of the soil explosion at a specific moment in the early stage of the explosion; the high-speed camera subsystem can record The dust diffusion process of the soil explosion; the laser transmission characteristic test subsystem can collect and store the echo data of the laser in the dust environment of the soil explosion; the trigger device can realize the simultaneous triggering of each subsystem. The invention can not only record the diffusion process of the soil explosion dust, but also obtain the echo data of the laser in the soil explosion dust environment, the test environment condition is controllable, the test is safe and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of explosion testing, in particular to an indoor soil explosion dust testing system. Background technique [0002] The short-range laser detection system has the advantages of high positioning accuracy, good directionality, strong confidentiality, good anti-electromagnetic interference, high sensitivity, safety and reliability, etc., and has been used in various weapon systems. In the process of ground combat, the dust caused by the soil explosion has a strong scattering and absorption effect on the laser, which will seriously affect the recognition ability of the short-range laser detection system and greatly reduce the accuracy of its detection. Therefore, it is of great significance to study the diffusion law of soil explosion dust and the transmission characteristics of laser in soil explosion dust to achieve accurate target identification and efficient damage. [0003] In recent years, researchers at h...

AI Technical Summary

Problems solved by technology

First, the existing soil explosion tests mainly focus on soil explosion cavity formation, explosion shock waves, and the damage caused by explosions to people and buildings on the ground. They rarely pay attention to the specific diffusion of soil explosion dust in the air. Transmission Characteristics in Soil Explosion Dust Environment

Second, there are few studies on the transmission characteristics of lasers in dusty environments, and the research mainly focuses on the dust generated by vehicles. There is almost no research on dust generated by soil explosions, and most of the research on the transmission characteristics of lasers in dusty environments is modeling Simulation research, lack of experimental verification

Third, the field soil explosion dust test has the disadvantages of uncontrollable environmental conditions, poor repeatability, high risk, high cost, and difficult testing.
