Numerical Analysis of Hydroelasticity Response of Ultra Large Container Ship Using CFD-MBD
With the development of the shipbuilding industry,the scale of ships continues to increase,and the natural frequency of ships decreases accordingly.Ultra large ships are also more prone to elastic and flutter in general sea conditions.Therefore,accurately estimating the hydroelasticity response is of great significance for ship design and navigation safety.This article uses a two-way coupling method based on CFD-MBD to numerically simulate the motion and hydroelasticity response of an ultra large container ship in waves.The calculation of the flow field is carried out using the open-source program OpenFOAM,and the structural part is calculated using the open-source multi-body dynamics calculation program MBDyn.The flow field and structural information are exchanged through PreCICE.By comparing the numerical results with experimental data,the feasibility of this coupling method is validated.A comparative analysis of hydroelasticity response in different wave conditions is conducted,providing reference for predicting the hydroelasticity response of ships.It was found that the container ship reached its maximum wave bending moment in the middle of the ship while sailing in a wavelength to length ratio of 1.
