Horizontal forced vibration experimental apparatus for FISHFRAM buoy segment model under action of inclined uniform flow

Abstract

The invention provides a horizontal forced vibration experimental apparatus for a FISHFARM buoy segment model under the action of inclined uniform flow, which comprises a buoy segment module, prosthesis modules, fixing modules, sliding modules and a measurement analysis control module. Both ends of the buoy segment module are respectively connected with the end part prosthesis modules. The fixing modules are respectively connected with the corresponding end part prosthesis modules and the corresponding sliding modules. The sliding modules are fixedly connected with the bottom of a trailer. The measurement analysis control module is arranged on the trailer and is respectively connected with the buoy segment module, the end part prosthesis modules and the sliding modules. In the invention, by arranging an optical fiber sensor on a fishing net, the local stress condition of the fishing net can be measured; by arranging component balances inside the buoy module, the overall stress condition of the fishing net can be measured; by arranging component balances outside the buoy module, the overall stress condition of the fishing net and the buoy module can be measured; due to the adoption of the special end part prosthesis module devices, the problem of the boundary effect of the model is solved; and the test condition can reach an actual KC value range and the scale effect is avoided.

Description

technical field [0001] The invention belongs to the field of marine engineering, and in particular relates to a horizontal forced vibration experiment device of a segmented model of a FISHFARM buoy that flows obliquely and uniformly. 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 ...
