摘要
阻力预测是船舶设计的重要环节。本文采用多种阻力预测方法对KCS船舶、KVLCC2船舶、Wigley船型以及NPL圆舭艇的阻力进行估算,验证多种阻力预测方法的计算精度和可靠性,探究各种阻力预测方法的适用范围。结果表明,基于回归分析方法计算常规排水型船舶阻力和基于细长体方法计算瘦长船型和方尾船阻力的方案可行。船型特征是选择阻力预测方法的首要因素。细长体理论计算的自由面波形结果基本令人满意。本文对船舶阻力估算方法的研究起到一定的借鉴和参考作用,同时也提供了一系列阻力计算的验证算例。
Resistance prediction is an important part of ship design.In this paper,the resistance of KCS ship,KVLCC2 ship,Wigley ship type and NPL round bilge boat is estimated by various resistance prediction methods,which verifies the calculation accuracy and reliability of various resistance prediction methods,and explores the applicable scope of various resistance prediction methods.The results show that it is feasible to calculate the resistance of conventional displacement ship based on regression analysis method and to calculate the resistance of slender ship and square stern ship based on slender body method.Ship type characteristics are the primary factor in selecting resistance prediction methods.The free sur-face waveforms of slender body are basically satisfactory.This paper provides some reference for the research of ship resist-ance estimation method,and provides a series of verification examples of resistance calculation.
