| 摘 要： | 文章利用MSC.Nastran软件对A级航区航标船两种不同工况下进行有限元分析。文中给出了边界条件施加方法和载荷计算方法。在甲板结构不满足强度要求的情况下,对甲板结构提出三种加强方案进行计算,结果显示船体主要构件强度满足规范要求,再对该船甲板结构的三种加强方案进行模糊综合评判,确定出最优方案,可为航标船的设计提供宝贵的经验。

| Abstract: | This article applies MSC.Nastran software to a finite element analysis of buoy tenders in grade A navigating zone in two cases,methods of imposing boundary conditions and load computing stated in the article as well.In the case of deck structure not meeting the strength requirements,it puts forward three reinforced schemes to compute the deck structure,which indicates that the strength of the main structure meets standard requirements.In addition,it makes a fuzzy evaluation of the three schemes and decides on the optimal scheme,which has a great reference value for the design of buoy tenders. |
