Abstract

Abstract

The secondary cross flow induced vibration of tube bundles of steam generator is the main failure reason of tubes. The flow induced vibration analysis and evaluations are based on the natural frequencies and modes of the heat transfer tube. A study on the dynamic characteristics of the heat transfer tube of a certain type steam generator have been carried out by calculation and experiment, and the natural frequencies and modes were obtained, and the relative deviations between measured and calculated values are within 8%.
