针对船舶阻力估算方法精度低和船型适用范围小的问题，提出一种适用于目前运输的三大主力船型的阻力预报方法，对艾亚法和兰泼凯勒法所估算的阻力值加以权重修正因子，然后将两者修正后的值相加即为最终估算的船舶阻力值，经权重修正法修正后的阻力值和试验值对比结果表明，其阻力预报精度明显提高，适用范围可扩大到目前三大主力船型。

To the rough precision and narrow application scope issue of ship resistance estimation method , a new forecast method is put forward which suits the resistance forecast of the three kinds of main ship forms in current shipping industry , in which the weighting correction factors of ψand φare introduced to respectively modify the calculation values of Ayre method an Lap-Keller method;and then the two modified values respectively are added together to obtain the final calculation value of ship resistance .The contrast of test value and modified resistance value by the new method shows that the precision of ship resistance forecast improves significantly and application scope expands to the three kinds of main ship forms .
