摘要:利用钢构网架对核岛钢衬里筒体模块整体吊装,在我国核电建设领域尚无先例。核岛钢衬里筒体模块整体吊装过程中的简壁变形间题,是其关键。利用网架吊装大型壁薄筒体时,网架的结构形式及其变形将直接影响到被吊装简体径向变形、筒体端部翘曲变形以及贯穿件周边的简体变形。核岛钢衬里筒体直径达44m,不仅壁薄,而且筒体自身重量以及附属的贯穿件、安装走道和吊具等总重量达
120t,这不仅增加了吊装的难度,而且具有一定的风险性
为保证筒体变形量在工程充许范围内,本文
基于ANSYS有限元分析软件,建立了吊装网架的参数化结构,对网架进行了整体结构位移计算和轴向应力分析。结果表明,钢村里简体模块整体吊装网架结构模型及其参数设置是合理可行的,对吊装网架进行模拟数据分析是必要的,为吊装网架结构设计和钢衬里模块整体吊装方案最终实施莫定了基础。关键调:核岛;钢衬里简体;整体吊装;网架设计;核电建设;ANSYS

Abstract; The use of the steel frame in the integral hosting of nuclear island steel lining cylinder module made a breakthrough in China's nuclear power construction.The deformation of the cylinder wall is the key issue in the integral lifting process of the nuclear island steel lining. Using the frame in lifting large and thin steel cylinder, the form of frame structure and its deformation will directly affect the radial deformation of the lifted cylinder, the buckling deformation of the distal cylinder, and the cylinder's deformation surround the penetrations. The diameter of nuclear island steel liner is 44 meters. The wall of the cylinder is thin,and the total weight of the cylinder itself and its
