摘要
波浪增阻是船舶在航行中经常遇到的问题,将波浪增阻理论研究结果运用于船舶设计中已成为可能.本文在分析了经典的波浪增阻公式之后,提出一种简化方法,使其计算不用数值积分而得出波浪增阻的近似值,从而简化了计算方法、提高了计算速度.同时给出了阻力影响函数的船型设计方法,通过实际计算,证明了在设计中考虑波浪增阻的必要性.
The calculation of added resistance is a common problem when ship sails in waves.It is found possible to use the achievement of theoretical research on the design of high speed ship.In this paper, according to the analysis, we properly simplify Maruo's formula of added resistance without resort to numerical integral.Thus, the speed of calculation is increased.Based on this, we develop an influence function method for ship form design.The investigation in this paper shows that when designing ship in service significent seas, it is of importance to take added resistance into account.
