Abstract

Abstract

Test method is used to research fuel’s natural characteristics and flow induced vibration responses. It obtained the natural frequencies, and responses rule that is flow induced vibration responses increased with flow increases. Then it achieved waterfall for amplitude, frequency and time（flow） on transient state; and movement trace of grid. The full and reliable test data will be an input for the design, safety analysis and fretting test; and support the safety evaluation.
