【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。
[Abstract]:The first floor structure of 28000 ton multi-purpose ship designed by Shanghai Shipbuilding Design Institute is selected as the research object, and MSC.Patran/Nastran finite element analysis software is used. Mooring and towing are carried out for all kinds of local strengthening structures of the bow. Calculation of strength checking for anchor winches, etc., to ensure that structures meet the relevant strength requirements of the code of china classification society. In combination with the code and other similar documents, the finite element model and load applied to the first reinforced structure checking calculation. The relative methods were compared and discussed. In particular, the application of MPC (multipoint constraint) element in the model is discussed, which provides a useful reference for the similar computation.

【正文快照】： 0引言船舶在营运中,经常要进行拖带和系泊作业,其拖带和系泊设备要承受较大的载荷[1]。由于船舶支撑结构强度不足导致船体结构破坏的事例时有发生[8]。为保证船在使用过程中的安全,中国船级社MSC/Circ.1175通函要求对拖带与系泊设备的支撑结构进行有限元强度分析[12]。主要考
