“育鲲”轮参数横摇的数值模拟及分析OA北大核心CSCDCSTPCD

In order to protect the safety of the vessel " YU KUN" , the numerical simulation and analysis of parametric rolling of the vessel were conducted. The susceptibility criteria for parametric rolling proposed by the American Bureau of Shipping ( ABS) were used to judge the occurrence of parametric rolling. Then, the mathematic model recommended by the International Towing Tank Conference (ITTC ) was employed to simulate and forecast the amplitude of parametric rolling. Using the susceptibility criteria and simulation of the mathematic model by a Matlab program, it can be seen that parametric rolling of the vessel " YU KUN" will occur while navigating, and the amplitude could even exceed 25 degrees, which may pose a threat to the safety of the vessel. The proposed method can quickly and validly judge and forecast the occurrence and amplitude of parametric rolling of the vessel " YU KUN".
