Horizontal forced vibration experimental device for sectional models of FISHFRAM float bowls flowing down uniformly

Abstract

The invention provides a horizontal forced vibration experimental device for sectional models of FISHFRAM float bowls flowing down uniformly, which comprises a float bowl sectional module, prosthesis modules, a fixed module, a sliding module and a measurement and analysis control module. Two ends of the float bowl sectional module are respectively connected with the end prosthesis modules, the fixed module is respectively connected with the end prosthesis modules and the sliding module, the sliding module is fixedly connected with the bottom of a trailer, and the measurement and analysis control module is arranged on the trailer and respectively connected with the floating bowl sectional module, the end prosthesis modules and the sliding module. An optical fiber sensor is disposed on a fish net, so that local stress conditions of the fish net can be measured, a component balance is arranged on the inner side of the float bowl sectional module so as to be capable of measuring integral stress conditions of the fish net, another component balance is arranged on the outer side of the floating bowl sectional module so as to measure integral stress conditions of the fish net and the float bowl sectional module, the problem of model border effect is resolved by the aid of the special end prosthesis modules, test work conditions can reach a real KC (Keulegan-Carpenter) number range, and 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 FISHFARM buoy section model under uniform flow. 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 th...
