Abstract

This paper deals with the applications of Pressurized Water Reactor fuel assembly vibration measurements by laser vibrometry. Two laser vibrometers are compared in terms of accuracy and handiness. One of them is a high precision integrated low powered device. The comparison of signals issued from simple experiments is made. The results are analyzed by using three classical modal analysis methods (logarithmic decrement, frequency band width, PRONY's method). This study will find applications in measuring the damping factor of fuel assembly by new signal processing methods.
