Abstract

The invention relates to the technical field of the hydrodynamic experiment and research, particularly to a vertical-multilayer-control-based internal wave making system and a control method thereof, wherein the system and the control method are used for generating a high-precision internal wave in a water tank or a water pool. The system comprises a water tank, a computer control drive system for generating a non-linear wave control signal, a mechanical transmission system, and a vertical wave making plate; and two layers of liquid with different densities are placed in the water tank. According to the invention, two dual-plate vertical wave making machines are controlled to different non-linear vertical speed distribution information are inputted into the d two layers of liquid with different densities, thereby realizing internal wave simulation in the water tank or water pool. The accuracy and precision are high; and requirements of different tests can be met.

Description

technical field [0001] The present invention relates to the technical field of hydrodynamic experimental research, and more specifically, to an internal wave generation system based on vertical multi-layer control and a control method thereof, which are used to generate high-precision internal waves in a water tank or a pool. Background technique [0002] In the field of ocean engineering and hydrodynamic testing, the wave maker is an essential device for physical model testing. The wave maker is usually set at one end of the test tank or pool, and waves are created by the reciprocating motion of the wave-making plate. Due to the complexity and diversity of experimental research, it is often required that wave generators can accurately generate waves that meet specific conditions. Most of the existing wave-making technologies in the vertical direction use a single plate to push back and forth flatly or swing, and the form of the vertical velocity distribution is fixed, or t...
