甲板开口对船体板架构件的刚强度影响分析

摘要

Opening and pectin deck in stress concentration problems and rigid problems had been a concern for shipbuilding designer.In this paper,the ANSYS finite element software is adopted to calculate hull decks with or without openings by finite element analysis,the stress and stiffness between variables compared.The final result shows that the stress concentration of the opening is quite obvious.%甲板开口与角隅处应力集中问题和刚性问题一直倍受船舶设计人员关注。利用有限元软件ANSYS对未开口和开口的船体甲板进行有限元分析计算，比较开口与未开口的应力以及刚性，其计算结果表明开口处的应力集中相当明显。
