FISHFARM float section experiment model

Abstract

The invention provides a FISHFARM float section experiment model which comprises a float section module, a first end prosthesis module, a second end prosthesis module and a measurement analysis module, wherein two ends of the float section module connect with the first end prosthesis module and the second end prosthesis module respectively, the measurement analysis module connects with the float section module, the first end prosthesis module and the second end prosthesis module respectively. According to the invention, through arranging a fiber sensor on a fishing net, local stress of the fishing net can be measured, through arranging a three-component device at an inner side of the float section module, integral stress of the fishing net can be measured, and through arranging a three-component device outside the float section module, integral stress of the fishing net and the float module can be measured; by employing a special end prosthesis apparatus, a problem of a model boundary effect is solved; experimental condition can reach a real KC number range, and a scale effect is avoided.

Description

technical field [0001] The invention belongs to the field of marine engineering, and in particular relates to a FISHFARM buoy segmented experimental model. Background technique [0002] The entire FISHFARM structure is placed in the sea, and its upper buoys and fishing nets will be subjected to the hydrodynamic effects of ocean currents and waves. Therefore, the dynamic analysis of the overall structure of FISHFARM is the key to whether it can be applied to engineering practice, and most of the methods used are model tests. [0003] However, most of the existing test models are the overall model of FISHFARM. In the limited space of the test pool, a large scale ratio needs to be adopted, resulting in too small KC number, which inevitably leads to scale effects. In addition, in order to simplify the research problem, in the study of FISHFARM's hydrodynamic response, theoretical researchers began to focus on decomposing the entire ring structure into many independent segments....

AI Technical Summary

Problems solved by technology

[0004] The purpose of the embodiments of the present invention is to provide a FISHFARM buoy segmented experimental model, which aims to solve the problem that the existing experimental model is limited to the overall model, the scale effect is large, and it can only simulate low KC number sea conditions, or can only measure the net clothing. The overall force is applied, and there is no problem of boundary treatment for buoy segments
