| 针对国内二代加的两环路核电厂试验用支管中存在的振动疲劳问题,提出了一种确定疲劳振动的测量和计算分析方法,并运用该方法对国内某两环路核电厂小支管进行了工况分析、振动测量和最大有效振动速度计算,同时采用结构力学有限元程序ANSYS软件对小支管的振动疲劳应力进行了分析.结果表明,该方法能够很好的诊断出小支管中存在的第一类敏感管和第二类敏感管,从而为判断在两环路核电厂中试验中支管是否是敏感管提供了理论依据. |

| As for the vibration fatigue problems existed in branch pipes used for domestic 2rd+ generation two-loop nuclear power plant testing,a measurement and calculation analysis method for identifying fatigue vibration is proposed,which is applied to carry out conditions analysis,vibration measurement and maximum effective vibration speed calculation for small branch pipes of a domestic two-loop nuclear power plant.At the same time,the structural mechanics finite element application program ANSYS is used to analyze the vibration fatigue stress of small branch pipes.The result shows,this method can diagnose the first type of sensitive pipes and the second type of sensitive pipes existed in small branch pipes,thus,it can provide theoretical basis for determining whether there are sensitive pipes in the branch pipes used for two-loop nuclear power plant testing. |
