Abstract
In order to avoid the impact of hull deformation on the shaft and other ship machinery, it is necessary to study the deformation of the ship under wave load. Firstly, The paper uses ANSYS element software dividing mesh of the whole ship, and then the APDL is used to calculate the dynamic pressure of wave. The results show that:under the same conditions,the hull with different deformation to the different phase of the waves, hull deformation showed a sinusoidal curve along with the movement of wave phase, with respect to 4m wave height, the shafting is obviously raised under 6m wave heights, but with smaller fluctuations in movement wave. Therefore, hull deformation is not the same under the different wave loading, hull deformation data can be the analysis conditions of shafting in different conditions of sea, and to analyze the effect of wave loads for other marine machinery.
