摘　　要：文章考虑材料非线性以及初始缺陷的影响,提出了球形缺陷厚壳的非线性稳定性计算公式,其理论结果与实验结果相符,同时文中采用有限元方法验证了该理论公式的正确性;采用理论公式,对缺陷幅值半径比在0.1%～0.5%之间、厚度半径比在5%～9%之间的一系列球形大深度潜水器耐压壳体进行强度和稳定性分析;参考潜艇规范,对球形大深度潜水器耐压壳体进行了优化设计。Considering the effect of material nonlinearity and initial deflection,the formula of nonlinear stability for spherical thick hulls with initial deflection is propesed.The theoretical result is found to be in agreement with the experiment result,and the correctness of this formula is also validated by the finite-element method.This formula is used to study the strength and stability of a series of spherical deep-submerged pressure hulls with fR in 0.1%～0.5% and tR in 5%～9%.Additionally,referencing deep-submerged specification,the optimum design for spherical deep-submerged pressure hulls is carried out.
