  • 발행 : 2002.11.01

초록

Recently, mixers are being widely used in the water purification plant in order to increase the filtration efficiency. The cause of an excessive vibration of a base structure to which the mixers are supported, has been evaluated through modal analysis on the mixer shaft and vibration measurements during operation. The fundamental natural frequency of the mixer shaft is found to be around 1.8 Hz and the main vibratory frequency around 30 Hz. (omitted)
