X-bow和Z-bow应用于高速圆舭艇上的阻力性能研究

阐述了X-bow的设计理念,并在其基础上提出了一种新型船艏——Z-bow.以一艘高速圆舭艇为研究对象,为了降低其在高速航行时的兴波阻力和飞溅阻力,对其船艏形状进行重设计:分别应用X-bow和Z-bow.建立原方案、X-bow方案和Z-bow方案的三维模型,利用Maxsurf软件中的SIT法计算各Fr下的阻力值.对计算结果进行了比较和分析,证明了高速圆舭艇上采用X-bow和Z-bow在阻力性能方面的可行性,且Z-bow的阻力性能优于X-bow.

Research On The Resistance Performance Of X-bow And Z-bow High Speed Round-bilge Crafts

The Z-bow design conception was proposed based on the X-bow, which was introduced in the paper. A high speed round-bilge craft was studied. In order to reduce the wave resistance and splash resistance when it sails at high speed, its bow shape was re-designed: X-bow and Z-bow was used respectively. Three-dimensional models of original plan, X-bow plan and Z-bow plan were established. By using SIT method in Maxsurf software, the resistance of each design plans at different Fr were calculated. According to analysis of the calculation results, it proved the possibility of applying X-bow and Z-bow to high speed round-bilge crafts in terms of resistance performance. And it showed Z-bow plan is better than X-bow plan.
