摘要：In this paper, based on lumped mass method and linear wave theory, a numerical model of the grid mooring net cage under waves has been developed by setting up the motion equations of floating system, net system, mooring system and floaters. In order to validate the numerical model, physical model tests have been carried out. According to our comparisons, the simulated results agree well with the experimental data. For single grid mooring system, there are three types of mooring lines, including bridle ropes, grid ropes and main ropes. According to our simulated results, forces in the three types of mooring line were calculated and analyzed. At the end of the paper, the hydrodynamic behaviors of net cage with the grid mooring system and four-point mooring system were simulated respectively, and the effects of mooring system types on the mooring line forces, the motions of floating collar and the net deformations of net cage were compared.
