Abstract:It is a very practical research topic to judge whether the dryer has accumulated water from its vibration characteristics.Based on the study of the structure and water accumulation state of the dryer of medium and high speed tissue paper machines， the vibration characteristics of the dryer with water accumulation were presented by means of the vibration basic equation and the motion mechanics model analysis.Using the self-developed vibration test platform to complete FFT analysis of the practice test data， it was concluded that the frequency spectrum analysis of the vibration signal from the bearings at the operating side of the dryer of paper machines， could be used to find the vibration characteristics of water accumulating which could be further used for online judgment of whether there is accumulated water in dryer of the medium and high speed tissue paper machines.
