摘　　要：以弹性回转壳理论为基础,推导圆锥壳与球形壳体的刚度矩阵与载荷列阵,建立了静水压力下考虑大挠度影响的环-球型端部舱壁强度与变形的理论计算方法。算例表明该方法与有限元数值方法计算结果相当吻合,也表明大挠度效应对该结构的强度与变形有一定的影响。研究表明,对于类似的回转壳体组合结构,进行解析分析是可行的,而且比常规的有限元方法更加准确和实用。研究结果对潜艇端部舱壁与压力容器球形封头设计具有重要指导作用。在现有研究的基础上,可以将该方法的应用范围推广至轴对称压力作用下的环-球型回转壳结构。A theoretical method is given in this paper to analyse the strength and deformation of ring-dome shell.Based on circular shell theory,rigid matrix and loading matrix of cone shell and dome shell are constracted,then the large deflecdtion is investigated.The results obtained with this method are good agreement with FEM’ results.It is proved that large deflection effect should be considered for ring-dome structure under external static pressure.It is also proved that the strength and deformation of rotate-shell structures can be calculated with analytical method.This method could be extended to the strength and deformation analysis of rotate-shell structure under axial-symmetry pressure.
