Abstract

The invention relates to the technical field of hydrodynamic experiment and search, and more specifically, relates to a nonlinear and multidirectional irregular wave and internal wave generating system and a control method therefor, wherein the system is used for generating high-precision nonlinear multidirectional irregular waves and internal waves in a pool. The system based on vertical multilayer and horizontal multi-plate control comprises a test pool (comprising a wave absorbing segment), a computer control drive system, a mechanical transmission system, a wave generating plate system (vertical multiple plates and horizontal multiple groups), and a wave height monitoring system. There are two fluid layers with different densities in the test pool during wave generating, or there is one fluid layer in the test pool otherwise. The system achieves the simulation of the nonlinear and multidirectional irregular waves and internal waves in the pool through the simultaneous control of a plurality of groups of horizontally arranged vertical multi-plate wave generating mechanisms and the different nonlinear vertical speed distribution of the two fluid layers or the single fluid layer, is higher in accuracy and precision, and meets the requirements of different tests.

Description

technical field [0001] The present invention relates to the technical field of hydrodynamic experimental research, more specifically, to a nonlinear multi-directional irregular wave and internal wave wave-making system and its control method, which are used to generate high-precision internal waves, Regular or irregular waves, linear or nonlinear waves. Background technique [0002] In the field of ocean engineering and hydrodynamic tests, wave generators are an essential device for physical model tests. The wave maker is usually installed at one end of the test pool 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. The existing wave-making technology is mainly based on the push plate type or swing type linear control system, which has the advantages of simple and intuitive, a...
