Description

Background
The structure water-entering problem has a wide engineering research background, and the launching of underwater weapons, the attack of ships, the landing of seaplanes, the water-entering of torpedoes and the launching of underwater vehicles all belong to water-entering devices. Although the water entering and exiting process of the structure is a very short transient process, the transient process has obvious characteristics, and relates to strong nonlinear free surface movement and crushing, turbulence and vortex, movement and deformation of an object, coupling interaction of the object and water and the like, so that whether the moving body can stably enter into another medium from one medium or not is determined to a great extent, and the process takes an extremely important position in the whole movement process of the moving body. Because the movement involved in the water inlet and outlet problem is very complex, the existing theoretical analysis method can not well and accurately analyze the physical process, so that a large amount of experimental research data and numerical simulation technology are mainly adopted to obtain approximate data at present. The data from experimental studies are often used to compare with numerical simulation results to verify the accuracy of numerical simulation techniques. Laboratory studies of water entry and exit problems therefore have an irreplaceable role in the study of water entry and exit processes.
In the prior art, patent CN106323590a discloses an object stabilizing multi-angle water inlet experimental device, which comprises a transparent water tank, an electromagnetic release device and a data acquisition system, wherein the electromagnetic release device comprises a support column and a vertical rod, one end of the vertical rod is hinged with a transverse support rod through a first hinge joint, and the other end of the vertical rod is hinged with an electromagnetic iron block with the bottom adsorbing a water inlet object through a second hinge joint; the horizontal water inlet angle adjusting pointer and the longitudinal water inlet angle adjusting pointer are vertically fixed on different sides of the vertical rod, the horizontal water inlet angle protractor is fixedly arranged on the horizontal supporting rod, the longitudinal water inlet angle protractor is fixedly arranged on the electromagnet block, and the electromagnetic release device is connected with the industrial control computer through a cable; the data acquisition system comprises a synchronizer controlled by an industrial control computer, a laser transmitter, a high-speed camera and a high-speed camera; the device can adjust the water inlet angle in the longitudinal and/or transverse dimensions, and adopts an electromagnetic control type release device, when the electromagnet block is electrified, the water inlet object can be adsorbed, after the electromagnet block is powered off, the electromagnet block loses electromagnetic adsorption force, and the water inlet object instantaneously falls into water.
However, the above-mentioned device has a disadvantage in that the water-entering object is released and falls into water in the form of free falling, and the water-entering speed cannot be adjusted, so that most of real water-entering conditions cannot be simulated, resulting in reduced experiment authenticity and reliability; in addition, the experimental water inlet is directly sucked in an electromagnetic adsorption mode, so that the experimental water inlet is effective for the metal material with smaller volume, however, the electromagnetic power consumption is larger for the experimental water inlet with larger bottom shapes (generally in a V shape) like ships, airplanes and the like, the reliability of positioning the experimental water inlet is reduced, experimental failure is easy to cause, and the experimental water inlet with nonmetallic material is difficult to adsorb.
The technical problems described above need to be solved.
