摘要
本文探讨了一种船舶兴波阻力理论。参照Noblesse的新细长船理论，用特殊函数将其中的被积函数展开，克服了原来形式的被积函数振荡产生的积分困难，形成较准机而且快速的算法；然后针对这种处理，按照基元波波陡有限的假设，对理论本身给予新的解释、从而对所述波陡院给出限制，得到一种新的兴波阻力计算方法，文中按其首阶近似对三种Wigley船型和包括系列60（Cb=0.6，0.7，0.8）的儿个船型的兴波阻力计算及试验结果比较，表明该方法简便有效。
A theory for ship wave resistance is explored in this paper. Expanding some factors in the integrand with special functions to facilitate the integration of highly oscillatory functions, results in a fast and accurate algorithm for Kochin function in the first approximation of Noblesse's New Slender Ship Theory. Based on the assumption of wave steepness limitation of elementary waves, the theory is reinterpreted by restricting wave steepness, in accordance to the above - mentioned algorithm, to develop a new method for wave resistance calculation. The comparisons between calculated and test results for three Wigley hulls and three practical ship forms, including S60(Cb= 0. 6, 0. 7 and 0. 8) hulls, show good agreement in a wide ship speed range.
