Natural Vibration Analysis of Tube Bundle in Steam Generator

A finite element model was established to research on natural vibration of tube bundle in steam generator. The support plate, flux distribution board, anti-vibration bar and loop hoop were researched on the effect of the natural vibration through finite element analysis method. The inside and outside fluids of the U-tubes were considered in this model too. It is certified that the structure and size of the anti-vibration bar and loop hoop have notable effect on the natural vibration.
