45°锻制嵌入式支管座结构应力分析与试验研究

Structural Stress Analysis and Experimental Investigation of 45° Forged Branch Insert Weldolet Fittings

采用有限元分析方法研究了内压作用下45°锻制嵌入式支管座接管结构的应力情况,得到了该结构的应力分布规律及失效位置。同时,开展了相应结构的爆破试验,通过试验数据对比验证了45°锻制嵌入式支管座的优越性。

Making use of FEA method,the stress distribution of 45° forged branch insert weldolet fittings was investigated to obtain the stress distribution rules and failure site. Comparing FEA results with experimental data from the blasting experiments verifies the advantages of 45° forged branch insert weldolet fittings.
