Liquid tank sloshing experiment integration device and using method thereof

Abstract

The invention discloses a liquid tank sloshing experiment integration device, which is characterized by comprising a control system, a liquid tank, a water inlet system, a water outlet system, and a data acquisition device, wherein the liquid tank is arranged above a motion platform; and the control system is respectively connected with the water inlet system, the water outlet system, the data acquisition device and the motion platform. According to the liquid tank sloshing experiment device with a compact structure, convenient assembly and disassembly, reliable connection, stable operation, strong practicability and realized integration, a motor system, the water inlet and outlet system, the data acquisition device and a high-speed camera are controlled through a single chip microcomputer, motion of three degrees of freedom of the liquid tank is controlled through the motor system, different carrier rates of the liquid tank are controlled through the water inlet and outlet system, pressure and wave heights at different positions are recorded through the data acquisition system, each process is coordinated for operation, the integrated experiment is realized, and as the water inlet and outlet system is connected with an underwater reservoir, circulating water use is realized, and the device is green.

Description

technical field [0001] The present invention relates to a new fluid physics experiment device and method, that is, an integrated device and method for liquid tank sloshing experiments, in particular to an integrated device for indoor simulating tank sloshing experiments of liquid cargo ships and its realization method . Background technique [0002] With the gradual large-scale development of LNG carriers, the liquid sloshing problem closely related to liquid cargo transportation has attracted more and more attention. In recent years, tank structural damage and ship capsizing incidents caused by severe liquid sloshing are not uncommon. Usually, during the ship’s navigation, under the action of sea waves, the liquid cargo ship will produce six degrees of freedom responses of rolling, pitching, yaw, sway, surge, and heave, and the magnitude of these responses directly affects the The course and navigation safety of the ship. The LNG ship carries low-temperature liquid natur...

Problems solved by technology

[0004] Among the published patents on liquid tank sloshing experiments, most of the implementation methods of liquid tank sloshing experiments have the disadvantages of complicated experimental steps, various experimental instruments, large space occupation, not compact structure and too much manpower in the experimental process. This experimental plan To solve the above problems, an automatic experimental device and its implementation method for accurately simulating the tank sloshing experiment under the coupling effect of three degrees of freedom of pitch, roll, heave and heave are proposed.
