Segmental generation method for waves in towing tank

Abstract

The invention relates to a segmental generation method for waves in a towing tank, which belongs to the technical field of marine engineering experimental research. The method is characterized by comprising the following steps that: when an irregular wave simulation experiment is performed in the towing tank, the length of the tank is limited, wave train data of irregular waves are relatively long, and a wave train generated by a wave generator is not finished when a tow truck runs on a track around the whole experimental site at the speed set in the experiment, so that the wave train is divided into segments, when a segment of wave train data are completed, the tow truck is returned to a starting point and is operated again in the next segment of wave train until the wave generator generates the whole train wave; and the acquired experimental data are integrated to form a group of complete wave spectrum simulation experiment processes. The method has the advantages that: the characteristics of irregular wave spectrums can be fully and truly reflected when an effect of the irregular waves on moving ships is researched in the towing tank.

Description

technical field [0001] The invention belongs to the technical field of ship engineering test research, and relates to test research on the effect of irregular waves on a moving ship model, and in particular to a method for creating waves by segmenting wave train data and integrating test data of each segment. Background technique [0002] At present, when studying the action of waves on the moving ship model in the towing tank, most of them use regular wave tests. Since regular waves are discrete into shorter wave train data, all their characteristics can be reflected, which is easy to implement. [0003] The actual ocean waves are irregular waves. When the irregular wave simulation test is carried out in the towed pool, due to the limited length of the pool and the relatively long wave train data of the irregular wave spectrum, the trailer runs on the track at the speed set in the test. The wave train generated by the wave maker may not have ended when the entire test area ...

Problems solved by technology

[0003] The actual ocean waves are irregular waves. When the irregular wave simulation test is carried out in the towed pool, due to the limited length of the pool and the relatively long wave train data of the irregular wave spectrum, the trailer runs on the track at the speed set in the test. The wave train generated by the wave maker may not have ended when the entire test area

Therefore, the current irregular wave test in the towed pool is also replaced by very short wave train data, which cannot fully reflect the characteristics of the irregular wave spectrum
