ASMEⅧ-2凹面受压椭圆封头计算浅析

Calculation Analysis of Ellipsoidal Heads Under Pressure on the Concave Side Required in ASME Ⅷ-2

本文以某产品为例,对ASME规范第Ⅷ卷第二册中凹面受压的椭圆形封头设计计算进行了简要阐述,分析了封头计算厚度大于筒体计算厚度的原因,及设计计算中主要考虑的因素。

To take the product for an example,the paper introduced the design calculation of ellipsoidal heads under pressure on the concave side per ASME code section Ⅷ divisionⅡ. Then ＂it analyzed whythe heads were more thicknessthan the cylinder. And the some necessarily noted problems were presented.
