摘　　要：借助国际通用的大型非线性有限元分析软件,对潜艇内部以加强平台取代水平横桁的平面舱壁结构的极限强度进行了非线性的有限元分析。阐述了单元及网格尺度的选择和求解控制策略;求得了结构的应力、应变分布规律;以及探讨了结构极限承载能力、破坏模式、塑性破坏机理。模型试验结果表明,试验值与有限元分析计算值吻合良好。Using general nonlinear finite element analysis program, ultimate strength analysis on plane bulkhead supported by inside deck of submarine is performed in this paper. The selection of element type and mesh scale as well as solution strategies are explained and the stress distributions on the structure are obtained by means of the foregoing program, and ultimate load-carrying capacity, collapse mode and mechanism of the structure plastic collapse are discussed. The experiment results presented by authors show that the experimental values are in accord with the calculated values.
