大型客滚船舱段屈曲和疲劳强度直接计算

Direct calculation of buckling and fatigue strength of large Ro-Ro ship section

    摘要
  • 摘要:
      目的  客滚船是一种高技术、高附加值的船型。由于其结构的特殊性，目前各国船级社还未形成统一的有关客滚船屈曲和疲劳强度的计算规范。
      方法  在充分分析客滚船结构特点的基础上，基于项目组自主研发的软件，依照挪威船级社（DNV）的客滚船屈服强度直接计算规范，并参考中国船级社（CCS）有关其他船型的相关规范，对某大型客滚船舱段进行屈曲强度、高级屈曲、热点疲劳3方面的直接计算，并详细介绍直接计算前处理设定方法，
      结果  结果表明，目标舱段的屈曲强度、高级屈曲强度及疲劳强度的直接计算结果全部满足规范值。
      结论  研究结果对大型客滚船的相关结构分析具有一定的参考价值。

     

    Abstract:
      Objectives  A Roll-on/Roll-off(Ro-Ro)ship is a modern ship type with high technology and high added value. Due to the specification of its structure, a consensus on buckling and fatigue checking for Ro-Ro ships has not been reached among the different classification societies of the world.
      Methods  On the basis of analyzing the structural characteristics of Ro-Ro ships, the present study considers the direct calculation of buckling strength, advanced buckling analysis and fatigue analysis of a selected section of a large Ro-Ro ship. The calculations are conducted on the basis of self-developed software from the SJTU KSHIP Project. The pretreatment of buckling and fatigue assessment are established in accordance with the DNV standard "Strength Analysis of Hull Structure of Roll-on/Roll-off Ships and Car Carriers", and the related CCS rules.
      Results  The calculated buckling strength, advanced buckling strength and fatigue strength of the target cabin meet the requirements of the related rules.
      Conclusions  The contents of this paper have a certain reference value for the related structural analysis of Ro-Ro ships.
