摘要

模块化设计和建造方法是AP1000第三代核电厂特点之一

但同时也面临着大型模块的吊装挑战。本文基于ANSYS大型有限元计算软件

对AP1000核电厂中大型结构模块CA01进行了吊装工况下的有限元分析

计算了结构的应力和变形

并对构件进行了规范验算。计算结果表明

在合理设置临时支撑的情况下

CA01模块能够安全吊装就位

为大型结构模块的顺利吊装提供强有力的理论支撑。

Abstract

Background: Modularization is one of characteristics of AP1000 nuclear power plant

however

the challenge of large module lifting should be met.Purpose: An analysis method for large module lifting has been studied in this paper.Methods: Based on ANSYS software and steel design code of America

the finite element analysis of CA01 structure module in AP1000 nuclear power plant was conducted.Results: The analysis results show that stress and deformation meet the requirements of codes and construction when the temporary brace is properly set in CA01 module.The maximum stress can be found in the juncture of wall

and maximum deformation occurs at the corner of CA01 module.Conclusions: Proper temporary brace is important to the lifting of structure and maximum stress or deformation usually occurs at irregular locations of structure.And it is necessary to perform detail analysis before structure lifted.
