基于STF切片理论对狭窄航道中低速船舶的纵向运动进行预报，开发适用于中低速船舶辐射水动力计算的程序，通过数值计算求得wigleyIII船模垂荡和纵摇运动的附加质量和阻尼系数，同时将计算结果与实验值进行比较，结果吻合较好，验证了程序的有效性。在此基础上，进一步分析不同水深和不同航道半宽对船舶附加质量和阻尼系数的影响。%The current study predicts the longitudinal motion of the ships in narrow channel with middle and low velocities by STF strip theory. A hydrodynamic calculation program for radiation problems is developed to numerically solve the added mass and damping coeffcient of a wigleyⅢ ship in pitch and heave motions. The program is validated by a good agreement of the numerical results with the experimental results. And the effects of depth and half width of the channel on the added mass and damping coeffcient are basically further investigated.
