Abstract
The invention belongs to the technical field of ocean engineering, and provides a deep ocean netting forced oscillation testing device considering the impact from flow velocity attenuation. The device comprises a fishing net frame module and a forced oscillation module. The fishing net frame module can be slidingly connected to a first vertical sliding module and a second vertical sliding module through a first connection module and a second connection module. The fishing net frame module is perpendicular to the first and second vertical sliding modules, and the first and second vertical sliding modules are respectively connected to the bottom of a trailer. A forced oscillation device is disposed on the trailer, and is connected with the fishing net frame module. The forced oscillation module drives the fishing net frame module to vibrate. The device carries out the sinusoidal oscillation or random oscillation through a forced netting module, so as to simulate the movement of water particles under the conditions of regular waves and irregular waves. The device employing the fishing ground netting module under the uniform flowing condition forces the front and rear nets to carry out oscillation at the same time, so as to simulate the flowing speed attenuation condition under the condition of a big KC number of waves.
