列举了管系中经常使用的几种主要的三通连接件的结构形式。利用数学模型对三通的受力进行分析 ,将三通结构的应力状态用薄壳理论来进行评价 ,得出三通所能承受的最大应力及需补强的范围
The structural types of several main tee connectors often used in pipelines are listed. Using the mathematical model to analyze the force of the tee, the stress state of the tee structure is evaluated by thin shell theory, and the maximum stress that the tee can bear and the range to be reinforced
