摘要
应用有限单元法对ＳＬ２（７） 型套管头结构进行应力分析，将套管头分成密封结构和承载结构２ 部分进行有限元应力计算，得到结构整体应力分布情况和单个构件的应力分布情况以及最大应力的分布位置，从而为ＳＬ２（７）
The structrual of SL 2 (7) casing pipe head was made stress analysis by applying the method of finite element.The casing pipe head should be devided into two parts in the process of finite element stress calculating,stress calculating of sealed structure and load supporting structure,the author obtains the results of global structure stress distribution,single member stress distribution and the location of the maximum stress.Therefore,the results can provide scientific basis for the structure design of SL 2 (7) casing pipe head.
