The invention provides an underwater explosion measurement system based on an electromagnetic equivalent load measurement method, a base provides support for a water tank and protects the water tank,and a support frame comprises a longitudinal guide rail, a lead screw, a guide block and a motor; a transverse frame comprises a transverse guide rail, a guide plate, a lead screw, a positioning tableand a motor; a measuring device comprises a sliding cylinder, a rigid sliding block, a magnet, a copper rod, a copper column and a confidential screw. Load generated by explosion acts on the rigid object block to enable the rigid object block to move, and the object block moves to push the copper rod to cut a magnetic field to generate current; the movement speed of the block can be obtained. Theunderwater explosion bubble pulsating load can be obtained according to a series of formulas such as the energy conservation law and the momentum conservation law. Based on the equivalent measurementmode, more accurate underwater contact explosion load parameters are obtained, and reference is provided for research work of underwater explosion load characteristics; and the system is low in costand simple to replace, and has wide application in the technical field of explosive destructive tests.
Description
technical field [0001] The invention relates to an underwater explosion measurement system based on an electric-magnetic equivalent load measurement method, and belongs to the technical field of underwater explosion bubble pulse impact test and measurement. Background technique [0002] The load measurement of underwater explosions, especially underwater contact explosions, has always been a research difficulty in this field. Due to the destructiveness of the explosion, it will damage the device during the measurement process, resulting in measurement errors and even device failure. And the measurement range of today's measuring devices is short, so it is impossible to measure the load of the explosion of high-yield explosives. [0003] For the experimental measurement of the underwater explosion load, nowadays it is usually a non-contact measurement, that is, the time history of the free field pressure is measured, and the load is obtained through numerical calculation.
