Experimental identification of unbalance in a rotor bearing system
Abstract
One of popular components in machinery is rotating elements (called rotor). Unbalance of rotor is the most common reason for the vibration of machines. This happens when the inertia axis of the rotating shaft does not coincide with the geometry axis one in which the bacrycenter of rotor is not positioned on the rotating shaft. Unbalance can damage important elements of machinery such as bearing, pad, gear or coupling…This problem need to be identified and reduced or fully eliminated. In this paper, authors proposed an experimental methodology to identify the unbalance of rotor. Acquired signal from proximity probes will be analyzed in order to obtain the matrix of influence coefficient [C] and the global matrix of coefficients [H]. Finally, value of position of the suitable masses are identified to reduce the unbalance of the rotor systems.
