联箱母管大开孔三种补强计算方法比较

本文对三种大开孔补强计算方法进行了详细对比计算,所用三种方法中两种为容器常用方法,一种为管道常用方法,计算结果证明了容器标准分析法的先进性,同时也说明了不同的方法适用范围不同,选用时应明确适用前提条件。对于容器和管道大开孔补强设计的相互借鉴提供了一种思路。

The Compare of Three Reinforcement Calculation Methods of Large Opening for Header Manifold

The three large opening reinforcement calculation methods are compared in detail, two of them are used in vessel commonly, one is used in pipe commonly, the calculation results show that the advancement of vessel standard analysis, also illustrate that different methods own different appli- cation scope, the applicable prerequisite should be clear during selection. A kind of idea is provided for learning from each other on vessel and pipe large opening reinforcement design.
