摘要
球形壳结构在耐压容器与潜艇耐压壳体设计中被大量使用。本文基于幂级数法建立了一种静水压力下考虑大挠度影响的球形壳强度与变形的分析方法。算例表明,本文提供的理论方法与有限元数值方法计算结果相当吻合,算例同时也表明大挠度对球形壳强度与变形有一定的影响。本文方法可以推广到轴对称压力作用下组合壳结构强度分析。
Dome shell is a common structure largely used in pressure vessels and submarine pressure hulls. A new theory method is given in this paper to analysis the strength and deformation of dome shell considering the large deflection effect base on power serials method. The＇results obtain by this method are good agreement with FEM＇ result. This method could be extending to combined circular shell structure under axial pressure.
