摘　　要：利用三维线性势流理论和源汇分布法研究潮流能电站载体的辐射问题，对不同水深下载体的附加质量和附加阻尼进行数值计算。计算结果表明，3个水平面运动（横荡、纵荡和首摇）附加质量随水深增大变化较为平缓，而3个垂向运动（垂荡、横摇和纵摇）附加质量随水深变化显著。载体的6个运动附加阻尼都随水深增加而增加，且波浪周期在4～9s时增幅较大。By using the 3-D linear potential theory, the radiation problem of tidal current energy power plant carrier is investigated and the hydrodynamic coefficients in various water depths are calculated numerically. It is shown that the added masses of heave, roll and pitch motions changes slowly with an increase in depth, while the added masses of surge, sway and yaw motions varies significantly. The added damping of all the motions of the carrier increased remarkably with an increase in depth,with a maximal increase slope occurs in the wave period is between 4 to 9 seconds.
