Nonlinear Finite Element Analysis for Out-of-Tolerance Holes Expansion in Tube Sheet of Steam Generator

  • 摘要: 本工作利用三维非线性有限元分析了某核蒸汽发生器管板的胀管效果,研究了尺寸偏差和材料特性变化等对胀管效果的影响,计算了几种典型传热管间隙和刚度下的接触压力,并与非超差管孔胀接触压力进行了对比研究,最后对合适胀管压力的选择提出了建议。

     

    Abstract: The tube’s expansion effectiveness in steam generator (SG) tube sheet was analyzed with 3-D nonlinear finite element in this paper. Tube expansion influences of actual size deviation and material characteristics were also researched. Through analysis, contact pressures of several typical tube gaps and tube stiffness were calculated and compared with the results of non out-of-tolerance holes. In the last, reasonable suggestions were provided for the selection of proper expansion pressure.
