摘要: 船舶弯道通航所需宽度计算的经验公式已有不少,但式中涉及的漂角值却都是试验测得。从弯道航行船模试验数据中对影响漂角的R/L、流速、航速和操纵性能等各主要因素进行了分析,运用量纲分析原理和线性回归分析,首次提出了弯道漂角计算公式。通过船模试验资料和实船试验资料验证,均有较好的吻合度。

Abstract: Though there have been many empirical formulas about the required width of navigation in curved channel, the drift-angle involved in the formulas is measured from tests. The main factors affecting the drift angle, such as R/L (R is the radius of curvature, and L is the ship length), flow velocity, navigation speed and maneuverability, are analyzed through ship model tests in curved channel. According to dimensional analysis and linear-regression analysis, the formula of drift-angle in curved channel is put forward. The calculated results are compared with data from ship model test and real ship test, and are validated to be consistent.

Key words: navigation in curved channel, drift-angle calculation, ship model test, regression analysis
