静水压力作用下的圆锥壳强度分析

圆锥壳结构在耐压容器与潜艇耐压壳体设计中被大量使用.文章建立了一种计算静水压力下圆锥壳强度的计算方法,利用幂级数法计算圆锥壳平衡微分方程的通解,通过构造变形函数利用Galekin法确定特解.算例结果表明文中提供的方法与有限元结果相当吻合,文中方法可以推广到轴对称压力作用下环肋圆柱壳结构强度分析.

Strength Analysis of Cone Shell under Hydrostatic Pressure

Cone 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 conical structure.The general solution of differential equation is expressed as power series solution and the particular solution is obtained by Galekin method. The results obtain by this method are good agree-ment with FEM' result. This method could be extending to ring-stiffened conical shell structure un-der axial pressure.
