基于ITTC的实船试航航速修正方法

依据ITTC 7.5-04-01-01.2,并结合ISO 15016（2002）中关于实船试航航速修正方法,以EXCEL为平台,通过VBA编写程序,建立了一种考虑风、波浪、水温、航行状态和浅水等影响因素的船舶试航航速修正方法,可以快捷方便地对试航航速进行修正,得到深水、无风、无浪、无流条件下的船舶航速、主机功率、螺旋桨转速及相应压载吃水和结构吃水工况下的S-P曲线。最后将软件应用于某散货船实船航速修正中,经对比分析表明其修正结果与船模试验的变化趋势是一致的。

Correction Method for Speed/Power Trials Based on ITTC

According to ITTC 7.5-04-01-01.2 and the correction method for the speed/power trials in parts of lSO 15016（2002）, a correction method considering the effect of the wind, wave, water temperature, trial conditions, the shallow water, and so on, is programmed by VBA on the platform of EXCEL, which can be used to quickly correct the speed and the shipping speed engine power, revolution speed and the S/P curves in light ballast and the scantling draft with no wind, no wave and no current can be showed At last, the software is applied to the real case, and the result by comparing and analyzing the correction result and the model test shows that the variation trend is the same.
