摘    要:以前的船模航速率定,是将初步试验结果用人工在坐标纸描点,连线拟合,从而确定船模航速率定参数的方法,不仅费时、费力,而且精度较差,对后续的船模试验将带来一定的误差。采用计算机对船模航速率定试验结果进行拟合将有效地克服以上缺点,并能对某些异常的试验结果进行修正,从而提高了整个船模试验的精度和可靠性。

关 键 词:船模航速率定  计算机拟合  最小二乘法

Abstract:The testing data of ship-models calibrating speed were handled by dotting and lining in a coordinate paper artificially before now. This method not only takes time and labour, but also the precision is not high, and the calibrating curve would bring certain errors in the after ship-model experiments. For overcoming the above mentioned short-comings, the testing data of ship-models calibrating speed may be fitted by computer, in which some abnormal testing data also modified. So the method can improve ship-model testings precision and reliability.
Keywords:ship-model speed calibration  computer fitting  least square method
