Experimental Balancing Technique by Trial Masses 2005-01-4006

This paper approaches the static and dynamic experimental balancing, applied to rotating machinery, considering the trial Weight Balancing. This method uses the Fast Fourier Transform (FFT), intending to determine the vibration signal (amplitude and phase) and to balance the system. This behavior occurs, because of the eccentricity of the center of gravity of th disk.
One of the objectives is to allow a precision balancing of rotating systems, in order to apply fitting process to balanced rotating systems, where it is possible to include a known unbalance, which can be use to check some fitting methods in laboratory.
The data acquisition is made by proximity sensors located at the disk or at the journal bearings. These data are processed by the software LabView, where the vibration signal is evaluated and the masses necessary to balance and their angular positions on the disk are determined.
