摘要：

A 3-D time domain program based on transient Green function method was developed to analyze hydrodynamic problems involving ship moving at a constant forward speed. From the point of view of the numerical accuracy and calculation efficiency, the precise integration method and some mathematical derivations were employed to evaluate the memory part of the transient Green function and its derivatives. And numerical tests were carried out for a Wigley-hull-form ship; the obtained results are compared with experimental data and reference results. Through the comparisons on the hydrodynamic coefficients, the reliability of the 3-D time domain program is confirmed. ©, 2014, China Ship Scientific Research Center. All right reserved.
