Paper Abstract

Acoustic intensity measurement techniques have been widely used for finding the acoustic power of a sound source from the acoustic energy flux in the space around it. Similar methods have been tried for measuring the vibration intensity or energy flux in plate structures, which require multi-point measurements with accurate information on phase differences. The present study extends the technique to web flutter in paper and plastic film manufacturing. The fundamental concepts of wave intensity are discussed, and the use of two laser-Doppler vibrometers is demonstrated. This study has application to flutter problems in paper dryers and in air-flotation ovens for plastic films.
