Abstract

This paper deals with a method detecting the unbalance forces of the rotor of rotating machines. Using this method, the amplitudes, phases and locations of unbalance forces of the rotor can be determinde simultaneously in the running case. In this paper, the load identification method [1,2] is used to identify the unbalance forces of the rotor on the basis of Modal Analysis of the rotor system. The method presented in the paper provides a theoretical basis for on — line identification of unbalance forces of the rotor of rotating machines. This method can also be used to balance the flexible rotor without trial weights.
