Force Modeling And Simulation On The Rounded Abyssal Cage

Nowadays the abyssal aquaculture cage is developing so fast that it becomes an necessary part for the sea farming industry. Improving the ability of anti-stormy waves is the important pledge for aquaculture. This paper describes the wave forces on abyssal cage and gives the kinetic simulation of this kind of cage on the basis of summarizing the actuality of abyssal aquaculture cage in China.Give the force equations with Newton Law and Moment Rule, gain the kinetic simulation and have a numerical count. Discuss the change of hydrodynamic force with the variation of wave-height, wave-length and wave-period. The hydrodynamic force change according to the regulation is that the horizontal wave force is much larger than the vertical wave force. in addition, the wave force changes remarkably with the variation of wave-height. This paper also describes the relation between submergence depth and wave-height, wave-length and wave-period. The conclusion is that the wave force varies rapidly in shallower sinkage. It will be different with the different cages. The reference point should be adopted is the mild point in the submergence depth-wave force curve. Using the software of Matlab Simulink to research the cage's moving simulation, and then workout emulator. At the beginning, the cage will change obviously. But with the past of time, it will be in a relatively steady position, and makes periodicity swing.
