| 摘 要： | 运用经典的线性兴波理论对浅水船舶兴波阻力特性进行了研究.针对浅水柯钦函数与深水柯钦函数之间存在的不相容性,通过引入深度影响因子来描述水深对浅水波阻的影响,重新定义了浅水柯钦函数,得到浅水线性波阻的一个新的表达式.借助量级分析和近似处理,导出了简化浅水柯钦函数和相应的浅水线性波阻公式.在上述工作的基础上,对浅水波阻特性进行了分析和讨论,合理地解释了若干实际现象.

| Abstract: | The wavemaking resistance characteristics of a ship in shallow water are studied with the classical linear wavemaking theory. In view of the incompatibility of the Kochin function for shallow and deep water,depth influence factors are proposed to take into consideration the effect of water depth on wave resistance in shallow water. The Kochin function for shallow water is redefined and a new expression for wave resistance in shallow water is obtained. The simplified Kochin function and the corresponding linear wave resistance formula for shallow water are derived by an analysis of the order of magnitude and approximation. The wave resistance characteristics in shallow water are discussed and some practical phenomena are explained. |
