Abstract

The invention discloses a device for simulating liquid sloshing generated under the random wave action. The device comprises a computer, a data collection module, an irregular wave generation module, a connecting rod, a base, a movement mechanism fixed to the base, a table board, a liquid cabin fixed to the table board, and a particle imaging velocimetry system. The particle imaging velocimetry system is right opposite to the front face of the liquid cabin, the irregular wave generation module is connected with the table board through the connecting rod, and the table board stably and transversely moves on the movement mechanism. The device further comprises a digital pressure sensor, a strain sensor, a wave height meter, a displacement sensor and an acceleration sensor. The digital pressure sensor and the strain sensor are embedded to the inner wall of the liquid cabin, the wave height meter is installed inside the liquid cabin, one end of the displacement sensor and the acceleration senor are installed on the table board, and the other end of the displacement sensor is fixed to the base. The device can accurately stimulate liquid sloshing generated under the random wave action in a small room.

Description

technical field [0001] The invention relates to a device for simulating liquid sloshing under the action of random waves and a wave-making method thereof, in particular to a small-scale indoor simulation test and measurement device for liquid sloshing of tanks of liquid cargo ships under the excitation of random waves, which are used in the field of ships and marine engineering . Background technique [0002] As we all know, ocean waves are random waves. Therefore, it is very necessary to study the hydrodynamic characteristics of the liquid in the tank under the action of random waves, and the model test is a relatively reliable method to study this problem. However, the current model test research mainly focuses on the research on liquid sloshing under simple harmonic excitation, and there are few reports on the nonlinear liquid sloshing characteristics in tanks under random wave excitation, and a lot of research work is still needed. The model test can not only comprehen...
