摘　　要：端部球面舱壁是一种组合回转壳结构,文章采用与回转壳相对应的弹性基础梁理论进行近似求解,考虑了厚薄板中曲面不一致引起的附加力矩和邻近肋骨的影响。该方法可应用于潜艇实际结构的设计计算。Based on the theory of elastic foundation beam,an analytical method for stresses of the end spherical bulkhead is developed.The effects of additional bending moment are accounted for in the present method due to the adjacent ring-stiffener of pressure hull and the mismatch of mid-section between the thick and thin plates.The numerical results show that this method can be used in the design and calculation of submersible pressure hull.
