摘要
介绍了核安全级阀门结构力学分析在安全评审中的重要作用。阐述了采用有限元分析法进行产品结构的三维力学分析技术的实用性和可靠性。以核二级电动截止阀为例 。
For the nuclear safety-related valve,structural mechanical analysis is obligatory during its safety evaluation.In the past,only the standard algorithm in the nuclear codes and some empirical equations were used because of the restriction of the analysis ability.With the development of the computer technology and the mechanical theory,three-dimensional structural analysis using the Finite Element Analysis (FEA) method is becoming mature and used widely in the structural analysis of the nuclear safety-related equipment.This paper introduces the procedure of structural analysis of a nuclear safety class 2 electric shutoff valve using three-dimensional FEA software.
