摘要
以某集散两用船为例,利用大型结构分析软件MSC Patran/Nastran,对该船尾部系泊设备下船体支撑结构建立尾部有限元模型,通过对系泊设备在各种组合载荷工况下的受力分析和强度计算,校核并完善加强结构设计方案,达到优选方案的目的,并满足相关规范要求,保证结构强度,保证船舶在运营中尾部系泊设备的使用安全以及对船舶尾部结构安全性的考虑。
A large structural analysis the tail finite element model of structural software MSC Patran/Nastran is used to establish supported mooring equipment reinforcer of a con- tainer and bulk carrier, the force analysis and strength calculation of mooring equipment under various combined load cases are carried out to check and improve the design of strengthening structure, the purpose of optimization plan is achieved, the relevant standards and require- ments are met, and the structural strength is ensured. This design is to be verified and opti- mized for guarantee mooring equipment reinforcing safety in shipping operation.
