Atmospheric chamber multi-diaphragm drivers for large blast wave simulators

Abstract

The invention belongs to the technical field of blast wave simulation equipment development in protection engineering, and provides an atmosphere chamber multi-diaphragm driver for large scale blast wave simulation equipment. According to the atmosphere chamber multi-diaphragm driver, both ends of a high pressure section (2) of an atmosphere chamber multi-diaphragm driver are respectively provided a wall supporting type reaction wall (1) and a diaphragm and high pressure packing structure (4), the center of the high pressure section (2) is provided with a high pressure gas chamber (3), the high pressure gas chamber (3) is communicated with a high pressure gas station, the main body of the diaphragm and high pressure packing structure (4) is formed by connecting a ring beam (14), a vertical column (11) and a cross beam (13), a plurality of frames formed among the cross beam (13), the vertical column (11) and the ring beam (14) are respectively provided with corresponding panels (15), and the multiple panels in the plurality of the panels (15) are fixedly provided with diaphragms (16) for linear cutting and drug loading. The atmosphere chamber multi-diaphragm driver has advantages of large high pressure gas chamber volume, more diaphragms, controlled number of the opened diaphragm, and controlled position.

Description

technical field [0001] The invention belongs to the technical field of development of an explosion wave simulation device in protection engineering, and in particular relates to a method for simulating the explosion of different equivalent charges by precisely controlling the pressure in a high-pressure gas chamber and the number and position of diaphragms and diaphragms opened on a high-pressure sealing structure. Atmospheric chamber multi-diaphragm drives for the resulting shock wave environment. Background technique [0002] Since the 1990s, due to the rapid development of high-tech weapons, new and higher requirements have been put forward for the experimental technology and experimental conditions of protective engineering. The existing shock tube equipment is limited by the loading environment and the size of the experimental section. Meet the growing experimental needs in many fields. In order to cope with the ever-changing military changes and improve the protection...

[0002] Since the 1990s, due to the rapid development of high-tech weapons, new and higher requirements have been put forward for the experimental technology and experimental conditions of protective engineering. The existing shock tube equipment is limited by the loading environment and the size of the experimental section. Meet the growing needs of experiments in many fields

This kind of driving system is relatively complex, expensive, and has high requirements on site conditions, and the time required for the gas in the driving tube to be evacuated is not easy to control
