摘要
采用对称与反对称教学模型,建立了等径直三通管件载荷及强度的分析方法,并编制了有限元计算程序TPW-1.针对各工况,计算了三通管件的应力,确定了三通管件的主要工况、合成工况及其应力分布曲线.实例计算结果与试验数据基本一致.
Some analysis methods of the load and strength for threeway of equal diameter are set up by symmetrical and adverse spometrical mathematical model, and a computer program TPW - 1 of finite element analysis is written. The stress ofthe threeway is calculated under different kinds of working conditions, and the main condition and combined conditions afid their stress distributive curves of threeeway pipe are determined. The calculation results of an actual example are basically in accordance with the data of the measurement.
