实船与船模相关因子的分析研究

Research on Correlation Factors between Ship Trial and Model Test

将某50 000吨化学品/油船在3种不同装载(满载、设计及压载)状态下的实船试航结果与船模试验预报进行了相关分析,获得了不同装载状态下实船试航与船模试验的功率相关因子CP及转速相关因子CN。对不同状态下实船试航结果与船模试验预报之间出现差异的原因进行了分析,提出了关于选用相关因子CP及CN值的改进建议,可供船舶研究及设计人员参考和选用。

In this paper,analysis of correlation factors is carried out based on the model test results and the sea trial data for a 50000-ton chemical/oil tanker under three loading condition(Full load,design load and ballast).The power correlation factor CP and revolution correlation factor CN are obtained in different load condition.The cause of the discrepancy between the sea trial and the model test results is analyzed and discussed.Suggestions for improvement of the correlation factors CP and CN used in ship model test prediction are put forward,which may provide a reference for relevant ship researchers and designers.
