Title:
UNDERWATER EXPLOSION PRESSURE TEST EXPERIMENT SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2020/206865
Kind Code:
A1
Abstract:
An underwater explosion pressure test experiment system and method. The underwater explosion pressure test experiment system comprises a container, an explosive material bag, a controller, protective glass, two high-speed cameras, a projector, a computer, an image analysis module and an explosion pressure calculation module; the container and the explosive material bag are used to simulate an underwater explosion scenario, the projector projects speckles on the water surface, the two high-speed cameras acquire images of fluctuation of a first water surface, the strain at a certain point on the first water surface is calculated using the speckles, a dimensionless parameter K value of the corresponding explosive material is calculated according to the strain and the elastic modulus of water, a change curve of underwater explosion pressures at different positions as a function of the distance from the explosion source is obtained by means of calculation according to a formula on the basis of the calculated K value, and the underwater explosion pressure at any point is determined according to the change curve. The underwater explosion pressure test experiment system is suitable for the measurement of an underwater explosion pressure.
