| 摘 要： | 以薄船理论的马丁法为基础,对船型横剖面面积曲线,加上考虑粘性作用产生的排挤厚度的修正,来计算兴波阻力。结果表明,计算值与试验值吻合较好,尤其是在中高速下,即F_n=0.4～0.7范围内,相对偏差不超过0.5％。在计算某型方尾军舰时,方尾产生的虚长度据试验得到的规律来确定。与其他方程比较,简单方便,且有较高精度。

| Abstract: | A corrected calculation based on the thin-ship theory with Martin method for viscous effect is suggested. The displacement thickness of boundary layer is superposed on the waterline area curve, that regarded as the viscous effect in wavemaking resistance calculation. The computative results show: This method is very simple, as well as considerably effective, specially for high speed range, such as Froud number Fn = 0. 4-0. 7, where the relative error is lower than 0. 5%. |
