应用面积增量函数改造横剖面面积曲线

The Transformation of Sectional Area Curve By Applying Area Increment Function

本文导出一种适用于无平行舯体船型面积曲线两维改造的简便方法。不需作数值积分和叠代计算,可直接应用面积增量函数δS(x)的精确数学解一次性改造面积曲线,同时变换C_B、C_M和LCB。易用性、精确性和可控性优于常规的纵向形变法,尤为适用于面积曲线和型线图的手工改造。

A simple method to transform sectional area curve in two dimensions suitable for ship forms without parallel middle body is presented in this paper, which can transform area curve one-steply with variation of C_B, C_M and LCB by applying the accurate mathematical solutions of the area increment function δS(x). The method is superior to the conventional method of longitudinal form variation in easy-useability, accuracy and controllability, and especially suitable for manual transformation of area curve and lines plan.
