摘　　要：用有限元分析方法 ,对带弓形不布管区废热锅炉换热器管板的结构进行有限元分析计算。在有限元分析模型中采用壳单元模拟管束、管板和筒体 ,采用杆单元模拟斜拉杆 ,并考虑管束对管板转角的约束。采用德国AD规范 ,计算管板厚度并比较两者的计算结果。通过分析可为工程优化设计提供依据。The finite element analysis of tubesheet of a waste heat boiler exchanger with arch region is presented in this paper. Modeling the FEM of the tubesheet structure,shell elements are used to describe the pipes, tubesheet and the shell of exchanger, link elements are used to describe the inclined poles, as well as the angular displacement constrained by pipes was accounted for. Compared the calculated results of the thickness of tubesheet with the AD Code of Germany. The results show that optimum design can be obatined by FEM analysis.
