摘　　要：本文针对大口径弯头,应用ANSYS有限元分析软件。先采用梁单元对管道进行整体结构分析。然后在整体结构分析基础上采用薄壁壳体单元对弯头进行局部有限元分析,可以得到弯头壳体应力的大小和分布规律。The object in this paper is a large diameter elbow. ANSYS, a finite element analysis software was used in this paper. Firstly, the pipeline was overall analyzed by using beam element. Then, the elebow was analyzed by using thin-walled shell element based on the overall structure analysis. The size and distribution regularities of elbow shell stress can be obtained by the local finite element analysis.
