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

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.
