Description

technical field

[0001] The invention relates to an underwater explosion experiment system. Background technique

[0002] Underwater explosion refers to the instantaneous release of energy from explosives, torpedoes, bombs or nuclear bombs in water, forming a shock wave that expands around and decays continuously in the water, and the shock wave interacts with structures such as ships to damage the structure. The underwater explosion process can be roughly divided into three stages: detonation of explosives in water, propagation and attenuation of shock waves, and oscillation and floating of explosion product balloons.

[0003] The explosive detonates first, releasing a large amount of energy instantaneously, forming high-temperature and high-pressure explosion products. During the expansion process, the high-pressure balloon is constrained by the inertia of the surrounding water, forming a spherical shock wave that propagates outward in the water, and at the same time, a sp...
