船舶操纵性指数计算方法的研究

On Calculating Method of Ship's Maneuvering Character Indices

在阐述了现行《船舶操纵》教材中关于船舶操纵性指数 ( K,T)计算方法的基础之上 ,提出运用曲线拟合的分析方法 .结合苏通长江公路大桥实船“Z”形试验所记录的原始数据 ,运用 MAT-LAB语言编写的程序进行计算、曲线拟合和作图 ,为船舶操纵性指数的计算了提供一个更趋于合理、简便。

Based on expatiation upon the K,T indices calculating method in lots of current maneuvering ship text book ,this article presents a new analysing method with curve simulating. Combined the original record data of zig zag experiment for Sutong Changjiang high way bridge ,the paper uses the MATLAB language program to calculate, imitate its curve and drawing a chart then offers a more reasonable calculating method for maneuvering indices ( K,T ).
