摘要
Abstract
The numerical analysis study on tube sheet structure of heat exchange has been an active domain of academics and engineering. In this paper, three kinds of simplified model for finite element analysis of tube sheet were founded: The non-porous equivalent solid sheet with bar element model (model A), the solid tube sheet with bar element model (model B) and the solid tube sheet with shell element model (model C). The results of three simplified models were compared with those of entire entity model (model D), It shows that model C is relatively close to model D in terms of stress intensity, axial displacement of tube sheet and tube axial force, the conservative solution is also obtained. The accuracy and efficiency of model C were satisfactory. The results in the paper provide the basis for the discussion of comparatively accurate FEA model for tubesheet.关键词
