【摘要】 为研究SMART堆蒸汽发生器螺旋传热管在正常工况下所受到的复杂应力,确定螺旋传热管上等效应力最大的位置以及热应力对螺旋传热管的影响,本文采用有限元方法,利用ANSYS有限元软件对韩国SMART堆蒸汽发生器螺旋传热管进行了热-流-固耦合分析,模拟计算得到螺旋传热管的应力、应变、位移分布。结果表明,螺旋传热管上应力、应变和位移的最大值主要依赖于系统温度。更多还原

【Abstract】 In order to research the complex stress of helical transferring heat tube of SG in SMART reactor under operating condition,confirm the largest equivalent stress position and analyze the impact of heat stress on the helical transferring heat tube,the finite element software ANSYS was used for thermo-fluid-solid coupling analysis in helical transferring heat tube of SG in SMART reactor,and the resulting stress,strain and deformation of the tube were calculated.The results show that the maximum values of stress,strain and deformation depend strongly on the temperature of the system.更多还原
