摘要
建立了天然气管道用汇气管的几何模型和有限元模型,对汇气管进行了有限元分析及强度校核,评定了汇气管正常操作工况下的疲劳寿命,认为有限元分析设计能解决常规设计不能解决的问题。
The geometry model and finite element model of header in the natural gas pipeline engineering were established.The strength of header were checked and analyzed,the fatigue life of header in the design pressure conditions was assessed.The summarization is that the finite element analysis can solve the problem that can＇t be solved by using the convention design method.
