摘要
本文用不确定度分析方法对船模拖曳阻力试验的精密度误差、系统误差及这些误差的合成误差引起的不确定度上极限提供数据估计,同时提出了一些改进测量误差的可行措施。为提高船模拖曳阻力试验的准确度提供了依据。
This paper presents a estimation for the upper limit of the uncertainty caused by the precisison error the bias error and their combined error in ship model towing resistance tests by a method of uncertainty analysis.Some effective steps to reduce the measurement error are also presented to provide an important basis for improving the accuracy of ship model resistance tests.
