The Effect of Clamping Force on the Wear Behavior of a Steam Generator Tube

Anti-vibration bars (AVBs) are essential components of a steam generator (SG) and used to prevent tubes (SGTs) from vibrating intensely because flow-induced vibration. However, the contact force generated at surfaces between AVBs can change natural frequency wear behavior tube. Contact is represented by clamping in this study. Considering effect on sliding distance SGT, dynamic under different forces was analyzed based finite element method, tube measured present work. Moreover, experiment conducted room temperature verify conclusions analysis. The increase reduces depth affected both also decreases.
