摘　　要：本文对潜水器的端部耐压隔壁在深潜状态下的应力和变形进行了计算,数学模型由截顶圆锥壳单元组成。本文给出了算例,计算结果与解析解、试验值颇为吻合。此外,还讨论了过渡圆半径与球面壳体半径之比r/R及半锥角α对环壳处最大应力系数的影响,结论是增大r/R或α,将使最大应力系数减小。In this paper, the stresses and deformations of the terminal pressure bulkheads of submersibles in the case of deep diving are calculated. The mathematical model is composed of the head-cut conical shell elements. The numerical examples are given and the results are in good agreement with those obtained by using analytical method and experiments In addtion, the effect of r/R and a on the maximum stress coefficient is discussed(r is the radius of transitive circle,R is the radius of spherical shell and a is the half of conical angle).The conclution is that the maximum stress coefficient will reduce when the r/R or a is increased.
