用加权残值法计算蝶形封头压力容器的极限载荷

THE EVALUTTION OF COLLAPSE LOAD USING MWR FOR VESSELS WITH DISC HEADS

摘要: 蝶形封头的压力容器具有广泛的工程应用。本文将其视为不同厚度的组合,采用加权残值法分析了各部分壳件的内力场,并计算了极限内压,得到一个简单的表达式。文末给出了一个具体算例。

Abstract: The internal forces of avessel with aise heads are sowed using MWR, and the collapse, load of the vessel canbe obtained dy satisfing the connection conditions of the uessel. A example is given.
