Embodiment Construction

[0014] The specific implementation manner of the present invention will be described in detail below in combination with the technical scheme and accompanying drawings.

[0015] When carrying out the irregular wave simulation test in the towed pool, due to the limited length of the pool, when the trailer 1 runs the entire test area on the track 9 at the speed set in the test, the wave train generated by the wave generator 10 may not be over yet, so , it is necessary to divide the wave train data into sections, and every time a section of wave train data is completed, trailer 1 returns to the starting point, and runs again in the next section of wave train. For example: it takes 20s for the trailer 1 to complete the entire journey, and it takes 80s for the wave generator 10 to generate a complete wave train. In this way, the wave sequence can be divided into 4 sections. Every time the wave generator 10 generates a section of wave train data, the trailer 1 Run it again, and fina...

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 ...
