| 摘 要： | 在对当前已建与在建的五万吨级大灵便型散货船的船型比较分析的基础上,确定了开发项目的主要尺度要素,并对该类船的线型特点进行了分析。利用势流计算原理对船体周围流场特性进行了计算分析,结合以往在船舶线型方面的经验对原船线型进行了改型优化,通过水池模型快速性试验验证获得了较为优良的船舶线型。在相同的主要尺度情况下,经对线型的改型优化可使满载状态时的有效功率下降23%,收到功率下降24%,设计状态时的有效功率下降20%,收到功率下降30%,相应的船速可分别提高0.6kn及0.7kn,说明对线型的改型优化取得了较为显著的效果。为采用兴波数值计算分析与船舶线型方面经验相结合的方法来进行线型优化提供了一个良好的范例。

| Abstract: | The ship lines feature and principal dimcntions of Haindymax Bulk Carrier are analyzed for the existing and inconstructing 50000 tons handymax ship in this paper.A new Handymax ship is estabilished,and the flow fied performance is calculated.Then the modified and oplimigeied ship forms are obteined and model tests are carried out.The results show that the effective power could be reduced down 23% and the received power could be reduced down 24% in the full load condition for the modified and optimizied ship... |
