Stress Analysis for Clad Steel Tube Sheet with Oval Tube Hole

摘要：

　　Models are established for oval tube hole clad steel tube sheet and circular tube hole clad steel tube sheet.Finite element analysis software ANSYS Workbench is used.Stress distribution characteristics of tube sheet with oval tube hole are investigated.Stress distribution characteristics under different ellipticity are analyzed and the general law of stress distribution of oval tube hole clad steel tube sheet is summarized.Results show: effects of tube hole shape on stress of clad steel tube sheet mainly focus in the tube zone,oval tube hole could effectively improve the phenomenon of stress concentration at the connection of basic layer and clad layer.When tube hole is oval,the maximum values of thermal stress and mechanical stress increase comparing to clad steel tube sheet with circular tube hole.With the increase of ellipticity,the total stress of tube sheet increases,stress increases on the minor axis of tube hole and decreases on long axis,and the deviation between the two stresses increases.The results provide reference for the design of the clad steel tube sheet.
