摘要
以最小湿表面积为目标,提出用二次曲线和幂函数曲线来生成船体型线。在已知船舶主尺度、设计水线、中纵剖线、横剖面面积曲线等参数的前提下,利用二次曲线和幂函数曲线的特性,编写程序自动生成一套光顺的船体型线。试验对比表明,生成船与母型船的阻力性能几乎完全一样,证明了这种船体型线生成方法的可行性。
Based on the idea of ship with minimum wetted surface area,a method was put forward by using quadratic curve and power function curve to describe the hull form.The details of quadratic curve and power function curve were studied,according to the parent ship′s main dimensions,designed waterline,the height of center buttock line and section area curve etc.A program was compiled to generate a smoothing hull automatically.Comparative trials of the automatic generation ship with the parent ship showed that the resistance performance is almost the same,which can prove the feasibility of this ship lines generation method.
