【Abstract】 An extended integral equation method was presented to remove the irregular frequency effects in solving the hydrodynamic coefficients for a ship-like floating body. The mixed source and dipole distribution model was adopted in the new boundary element method in which the singularities are distributed along the body surface and water line inside the body. It is showed that the proposed integral equation has unique solution and consequently the irregular frequencies effects are removed. Numerical calculations for the hydrodynamic coefficients of ship like cross sections demonstrated the effectiveness of the new method.更多还原
