Abstract
The embodiment of the present invention discloses an underwater explosion pressure test experiment system and method. The invention including: container and drug pack are used to simulate underwater explosion scenes. Projector projects scattered speckles on the water surface. Two high-speed cameras collect images of the first water surface fluctuation. The strain at a certain point in the first water surface is calculated according to the scattered speckles. The K value of the corresponding explosive is calculated from the elastic modulus of the strain and water, and based on the calculated K value, the curve of the explosion pressure at different points in the water with the distance from the explosion source is calculated according to the formula, and the explosion pressure at any point in the water is determined according to the curve. The invention is suitable for use in an underwater explosion pressure measurement experiment.
