Pressure relief type deepwater environment simulated explosion testing device

Abstract

The invention belongs to the technical field of underwater explosion researches and particularly relates to a pressure relief type deepwater environment simulated explosion testing device. The testing device comprises a pressure vessel with a top opening, wherein a pressurizing hole is formed in the side face of the pressure vessel, a pressure relief flange is mounted at the top opening of the pressure vessel, and a static pressure measuring hole, an impact wave pressure measuring hole and a detonation hole are formed in the pressure relief flange; a pressure gage is mounted at the static pressure measuring hole, and sealing flanges are separately mounted at the impact wave pressure measuring hole and the detonation hole; an impact wave pressure measuring device is mounted at the impact wave pressure measuring hole, and a detonating device is mounted at the detonation hole. According to the pressure relief type deepwater environment simulated explosion testing device, the pressure relief flange is arranged at the top of the pressure vessel, the pressure relief flange will be broken away from the pressure vessel after explosion impact pressure reaches a certain value when a deepwater environment simulated explosion test is carried out so as to play a role in relieve pressure, and thus, the bearing capacity of the pressure vessel is not restricted to the volume and wall thickness of the pressure vessel any more, so that the equipment cost and test difficulty are greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of underwater explosion research, and in particular relates to a pressure relief type simulated deep water environment explosion test device. Background technique [0002] Underwater explosion is the theory, method and means of studying the explosion generation, evolution, propagation, and interaction with underwater targets, involving multiple disciplines such as ship and ocean engineering, mechanics, and material science. Due to the complexity of underwater explosion, it is very difficult to conduct detailed theoretical research on it and attempt to completely resolve the underwater explosion problem by establishing an accurate mathematical model. Therefore, it is very difficult to conduct some experimental research on underwater explosion. very necessary. [0003] Deep-water explosion tests are expensive, long-term, and difficult to implement. At present, only a few countries such as the United States ha...
