为了探究球鼻艏宽度与船舶快速性的关系,在对某渔政船的主尺度和机型已定的情况下,针对相同船型设计了三种不同宽度的球鼻艏,利用maxsurf软件中的新细长体理论,首先计算原船的兴波阻力系数和有效功率,并将计算结果和船模试验值相比较,结果表明该方法和试验值较为接近;接着计算三种不同球鼻艏的船的兴波阻力系数和有效功率。结果表明适当增加球鼻艏的宽度可以减小船舶的兴波阻力,提高船舶有效功率,进而提高了船舶的快速性。
為瞭探究毬鼻艏寬度與船舶快速性的關繫,在對某漁政船的主呎度和機型已定的情況下,針對相同船型設計瞭三種不同寬度的毬鼻艏,利用maxsurf軟件中的新細長體理論,首先計算原船的興波阻力繫數和有效功率,併將計算結果和船模試驗值相比較,結果錶明該方法和試驗值較為接近;接著計算三種不同毬鼻艏的船的興波阻力繫數和有效功率。結果錶明適噹增加毬鼻艏的寬度可以減小船舶的興波阻力,提高船舶有效功率,進而提高瞭船舶的快速性。

In order to study the relationship between the width of bulbous bow and the ship speed, three kinds of bulbous bow with different width are designed for the same ship under the condition that a certain fishery administration ship’s principle dimension and host type has been set. First, the wave resistance and effective power about the original ship are calculated by maxsurf and the result and test value are compared. Result shows it is close to the test value. Then the wave resistance and effective power of the three kinds of ship are calculated. The result shows that proper increasing of the bulbous bow width maybe one of the best way to reduce the ship wave resistance and improve ship effective power and the rapidity of the ship speed.
