摘要
本文根据线性理论的基本假设,并应用多点纵切法非定常波形测量与分析的结果,建立了船舶在规则波中迎浪航行时的非定常兴波柯钦函数与船型的关系和波浪增阻影响函数的表达式。柯钦函数的理论计算与波形分析实验结果的比较表明,两者吻合很好。这说明波浪增阻影响函数可以作为高速船舶最小阻力船型设计与改进的基本依据。文中还讨论了增阻影响函数的性征与变化规律。
Based on linearlized potential theory and test results and corresponding analysis of unsteady waves generated by a ship model runing at constant forward velocity in regular head waves, a practical method is proposed for the improvement of ship forms according to the relationship of kochin function with ship hull geometry, and expressions of the wave added resistance influence function are established.The theoretical calculation of Kochin function are in accordence with the experimental results from wave pattern analysis.It is pointed out that the influence function of added resistance in waves can be used for the design and modification of ship form of high speed ship with least resistance.
