核电厂主设备开孔结构有限元分析方法对比研究

Comparative Research of Finite Element Methods for Perforated Structures of Nuclear Power Plant Primary Equipments

核电厂主设备会使用许多结构复杂、形式不一的开孔结构。为了探索其力学分析及评价方法,对开孔结构进行有限元分析方法与等效解析方法对比研究。研究中考虑了影响开孔结构计算分析的主要因素(包括各种开孔形式、排列方式等),系统地梳理出开孔结构的有限元分析方法。

Many perforated structures are used for nuclear power plant primary equipment,and they are complex,and have various forms.In order to explore the analysis and evaluation method,this paper used finite element method and equivalent analytic method to do the comparative analysis of perforated structures.The paper considered the main influence factors （including perforated forms,arrangements,and etc.）,obtaining the systematic analysis methods of perforated structures.
