| 摘 要： | 选取上海船舶设计院设计的28 000吨多用途船的首楼结构为研究对象,采用MSC.Patran/Nastran有限元分析软件,针对船首各类局部加强结构分别进行系泊、拖带、锚绞机等强度校核计算。确保结构满足中国船级社规范的相关强度要求。同时结合规范以及其他同类文献对首部加强结构校核计算中的有限元建模与载荷施加的相关方法进行对比探讨,尤其论述了模型中的MPC(多点约束)单元的应用,为同类计算提供有益的参考。

Statics analysis of alongside-arranged highline cable replenishment system at sea based on catenary equation |
| |
| Abstract: | Statics analysis model is established based on catenary equation for alongside-arranged highline cable replenishment system at sea after considering influence of cable’s length and weight. Effects of several parameters, including cable’s unit weight and tensile force, are then discussed. It is found when the ratio of horizontal tension to cargo weight exceeds 4, the deflection of highline cable is ignorable to safely transfer cargos. |
