摘　　要：基于三维Rankine源方法,进行三体船附加质量和附加惯性矩计算,分析了片体干扰对三体船附加质量和附加惯性矩的影响,为三体船操纵性预报奠定基础。通过对圆球、椭球附加质量和附加惯性矩的计算,以及对三体船附加质量和附加惯性矩定性规律的分析,说明了文中方法的可靠性。研究表明,片体干扰对三体船附加质量和附加惯性矩有一定影响,但并不十分明显,且这种影响随着间距的增大很快衰减。Based on Rankine panel method, the trimaran additional mass as well as additional inertia moment was calculated and the interactive influence among three bodies to them were analyzed, which is the basis of the trimaran maneuverability prediction. The additional mass as well as additional mo- ment of a ball and ellipsoid was calculated, and the qualitative rules for trimaran were analyzed. The analysis validated the method. The result shows that the additional mass as well as additional moment of the trimaran can be influenced by interaction among three bodies, but not quite obviously, and the influence will decrease quickly while the distance between bodies increases.
