基于ANSYS壳单元与三维实体单元的锅炉管板分析

摘要

Currently, ifnite element analysis of the pressure vessel is mainly based on three-dimensional solid modeling. The models from SHELL63 elements in ANSYS are used to analyze the stress of tube plate in this paper. Analysis of the heat pipe weld using of the results of SHELL63, and verify that it meets the strength requirements. At the same time, we give a pressure vessel analysis method by ANSYS.%目前压力容器的有限元分析主要是基于三维实体建模。本文用ANSYS软件的SHELL63对废热锅炉进行整体建模，并分析管板的应力分布。利用整体分析结果对导热管焊缝进行分析，验证其满足强度要求，同时给出一种利用ANSYS计算压力容器的方法。
