摘 要: | 为评定船舶操纵性试验结果的可信度,基于ITTC 7.5-02-06-05的指导意见,对船模回转试验的不确定度进行分析。基于自由自航模回转试验方法,对某型船进行重复性试验,获取试验相关的不确定度。数据分析结果表明,在置信区间为95%、置信因子为2的条件下,船模试验回转直径的不确定度为4.9%,结果可信,具有一定的工程应用参考价值。

Abstract: | The credibility of the turning circle test results is examined following the guidance of ITTC 7.5-02-06-05.Repeated tests are performed on one type ship with free running model.The tests show that under the condition of 95%of the confidence interval and confidence factor of 2,the uncertainty of the turning diameter is 4.9%.The model test results are credible and of engineering reference value. |
