Abstract

The invention discloses a passive measurement device for the working capacity of air shock waves of small-equivalent explosive explosion, and aims to overcome the defects that an existing measurement device is complex in post-processing, easy to be interfered by electromagnetic interference, low in sensitivity and measurement precision and the like. The device is composed of a sealing shell, two driving sliding blocks, two cutting components, two energy absorption components, two sealing baffle rings, a sealing bolt and an air hole. The two driving sliding blocks, the two cutting components and the two energy absorption components are symmetrically installed in the sealing shell with the explosive as the center. According to the invention, shock wave energy is quantitatively converted into cutting embedding displacement of the blade to the energy absorption component by using the energy absorption component, and rapid quantitative passive measurement of shock wave power capability in an explosion field is realized. The device can effectively measure shock waves with different intensities and proportional distances, and is suitable for measuring the power capability of the explosive in a closed space. The device is simple in structure, does not need power supply, is convenient to arrange and use, and can be repeatedly used.

Description

technical field [0001] The invention belongs to the field of energy detection, and in particular relates to a device for testing the working ability of air shock waves produced by the explosion of small-equivalent explosives. More specifically, it relates to a device for testing the working ability of explosion shock waves in a closed space by using structural energy-absorbing characteristics. s installation. Background technique [0002] When the explosive explodes in the air, high-temperature, high-pressure, and high-speed explosion products are produced instantly, and then the adjacent air medium is compressed violently, making its pressure, density, and temperature rise step-by-step, forming air shock waves, and spreading outwards . The air shock wave is one of the main factors for the damage and destruction effect of ammunition explosion on personnel, equipment and protective structures. Therefore, accurate measurement of the working ability of the air shock wave is of...
