【摘要】 基于肥大型船的快速性试验数据,通过对传统估算公式结果的分析及船舶伴流成因的研究,选定部分船型参数及无因次量作为影响因子,建立线性数学模型,采用逐步回归法得到一种新的、更加精确的肥大型船伴流分数估算方法,通过实例验证其精确性和正确性。更多还原

【Abstract】 Based on dozens of the speediness test data of full form ships,through the analysis of the traditional estimation formula and the study on formation cause of the ship’s wake,part of ship form parameters and dimensionless quantity were selected as impact factor to establish the corresponding mathematical model.A new,more precise full form ship wake fraction estimation method was proposed by stepwise regression,whose accuracy and correctness were verified by some computation.更多还原
