船体结构钢夹层板强度计算方法研究

摘要

对不等厚度表层的钢夹层板(SPS)强度分析方法开展了研究。建立了基于Hoff理论的钢夹层板位移模式，推导了钢夹层板强度计算的微分方程组，并求其解析解。在假定双级数解形式的基础上，获得了在均布载荷作用下，四边自由支持的不等厚度钢夹层板的解析解，并给出数值计算示例。%A new method analyzing the strength of sandwich plate system (SPS) with different thickness is developed in the paper. SPS finite element is established for finite element analysis and for strength calculation. Calculation and analysis are available for strength of ship SPS through this work.
