摘要：
In this paper, the CFD-FEM two-way coupled method is extended to simulate the asymmetric motions and wave load responses of a ship in oblique regular waves considering hydroelasticity effects. The numerical results of ship motions and loads including time series and response amplitude operators are validated by comparing with the tank experimental results. Then the ship motions, vertical bending moment, horizontal bending moment and torsion moment in oblique waves are analyzed in both time domain and frequency spectra; and the influence of wave height, wave length and ship speed on the results are systematically analyzed. Moreover, the correlation between horizontal bending moment and torsion moment as well as their component loads is analyzed by crossspectral analysis method. The effect of springing responses corresponding to the bending-torsion coupled mode on the sectional loads is also discussed.
