水面舰船总强度标准应用研究

Study on hull-girder strength criteria of naval ships

由于现有国内水面舰船设计规范仅适用于船长160m以下的舰船,有必要提出适用于船长160m以上的水面舰船结构设计标准,本文着重讨论了水面舰船总强度标准,综合分析和比较了现行规范对总强度的相关规定,并在整船三维有限元强度分析的基础上提出了当船长超过160m并接近200m时船体的总强度标准的建议,最后给出了设计目标船的结构设计校核应用实例。

The rules for naval ships are not applicable to the ships which are above 160 m. It is necessary to recommend structural design criteria for this kind of ships. The hull-girder strength criteria of naval surface ships was studied. On the basis of 3-D FEM (finite element method) calculation on global longitudinal strength, recommendation of the hull girder strength criteria was made for a ship with length of about 200 m. The example of structural design and check was also presented for the given ship. The result shows that this recommendation is reasonable and available.
