| Abstract: | This paper adopts the spectral method to do the fatigue strength evaluation and the principles of spectral method is discussed. As a large container ship for example, the FEM model of global ship is built by MSC.Patran, the wave load is calculated by three-dimension linear potential flow software Compass-Walcs, the wave load and cargo inertia force is automatically applied by using PCL language. The fatigue strength evaluation for typical structures of large container ship is performed based on S-N curve and the principles of Miner linear accumulation damage. |
