Abstract
The dynamic analysis model of cap considering structure-water interaction is built up, based on potential fluid theory. A double-layer water mesh generation method is suggested to simplify the modeling process. The influences of different parameters of the rectangular cap and the one with complicated chamfer on the hydrodynamic effect are investigated using the proposed methods, including the cap vibration frequency, the geometrical size, the chamfer and the submersion depth of the cap. The study indicated that the cap vibration frequency has little effect on the hydrodynamic effect; the increase of the ratio of the length to the width or the thickness will increase the hydrodynamic effect; The form and size of cap chamfer both have significant influences on the hydrodynamic effect, and ignoring the existence of the chamfer will amplify this effect; the hydrodynamic effect will increase with the increase of the submersion depth of the cap, while keeping in constant after the depth exceeds a certain value.
