| description | The vibration of large containerships induced by waves and its resulting fatigue damage have long been the focus of research in the field of ocean engineering. For low-frequency nonlinear wave-induced springing, potential flow and viscous flow remain the two significant calculation methods. Based on potential flow theory, this study investigates the nonlinear wave-induced vibration response of large containerships, including the superposition of sum and difference frequencies, by considering the influence of second-order hydrodynamic forces. Meanwhile, a three-dimensional numerical wave basin model is established to simulate fluid–structure interaction, integrating structural mode superposition for two-way CFD (Computational Fluid Dynamics)-FEM (Finite Element Method) coupling. By comparing with the experimental results, it is found that the frequency-domain nonlinear method considering second-order hydrodynamic forces and the CFD-FEM method can both effectively capture the nonlinear wave-induced vibration phenomenon under regular wave conditions. The numerical simulation results of the two methods are close to the experimental results. Moreover, the frequency-domain nonlinear method has a fast calculation speed, making it more suitable for the preliminary design of large ships. |
