带平齐接管的椭圆封头大开孔边界效应理论与实验研究

Theoretical and Exper Imental Researches On the Boundary Effect of Large Opening Ellipsoidal Head With Flush Nozzle

本文在文献[1] 的基础上用薄壳理论分析了椭圆封头上大开孔平齐接管边界效应问题 ,用实验数据进行了验证。验证结果表明 ,除了焊缝区之外 ,本文提出的计算理论是可靠的。

On the basis of reference [1] ,the boundary effect of ellipse head with flush nozzle in large opening hole is analyzed with Thin shell Theory in this paper.Then the verification using experimental datum is carried out.The results showed by verification that,outside the range of weld joint,the calculation theory proposed by this paper is reliable.
