Hydrodynamic Pressure Distribution on Ship Hull At Very High Encounter Frequencies

摘要

New developments to improve the wave diffraction and radiation solution are presented in the present work.They consist of the implentation of the supplemented boundary integral equation method to remove irregular frequencies,and the analytical integration of the wave terms in the Green function over a flat panel to ensure the numercal precision at high wave encounter frequencies.The hydro-structral interface is realized by recomputing the hydrodynamic pressures at points of structural model and the hydrodyanmic coefficients (addedmass and radiation damping) and wave excitation loads are computed following each mode of structural model Thisprovides a perfect eqiillibrium between inertial and pressure loads on the strctural model.
