In recent years, the trend in the design of rotating machinery has been toward reduced weight and increased operating speeds, with the objective of increasing operating efficiency and thus reducing cost. However, these more efficient designs result in increased rotor flexibility and are, in general, more susceptible to a variety of undesirable rotordynamic phenomena. In particular, increased rotor flexibility substantially complicates rotor balancing requirements. Control of rotor vibration is necessary to maintain reasonable noise levels and to ensure operator, and consumer safety, and machinery survival. In general, the operating expense of rotating machinery is a direct function of the success with which rotor vibrations are controlled.
