摘　　要：通过新的高强度钢材环肋圆锥壳模型实验，及采用解析方法分析表明，环肋圆锥壳体破坏的原因是结构相对薄弱处纵剖面上的中面应力所致．并提出用“灰色系统”理论预测破坏载荷的计算方法。Through model test of new high- strength steel conical shell with ring frame,and relevant analysis,it is shown in this paper that the failure of ring-framed conical shell can be traced to the neutral plane on longitudinal section where the structure strength is relatively weak.It puts forward a calculation method for predicting failure load using “Grey System”theory and suggests to use this method in model experiment for pressure hull of the active submarine in the future.
