摘　　要：提出在静水力曲线、邦戎曲线以及船形稳度力臂插值曲线计算中对附体处理的一种新方法,即建立在三次样条插值函数积分基础上的附体体积分布法.该方法将附体按体积与体积中心等效的条件分布到船体型值点上,其中船体体积与体积中心采用三次样条插值函数积分法进行计算,以此来修正其对船舶静力计算结果的影响.按该方法对某船带附体的静水力曲线、船形稳度力臂插值曲线进行了计算,并对计算结果进行了分析,表明该方法在工程应用中可获得满意效果.This paper puts forward an appendagesdisposal method in the ship stability calculation, which is based on the three order spline interpolationfunction integration. It can be used in the ship stability calculations, such as the hydrostatic curve calculation, Bonjean curve calculation, ship form stability arm interpolationcurve calculation, etc. The appendage effectis included by the hull offset incrementaround the appendages. As a tentative conclusion, such a method can obtain satisfactoryresults in the practical engineering calculation.
