Procedures for Balancing Flexible Rotors
This standard classifies rotors into groups by their balancing requirements as influenced by the rotor's flexural stiffness and unbalance distribution. Certain classes of rotors may be balanced by normal or modified rigid rotor techniques. Other more flexible rotors may require high-speed balancing. The fundamentals of flexible rotor balancing are discussed as well as methods of assessment of final unbalance. Guidance is given on judging the final balance quality, however, this standard is not intended to serve as an acceptance specification for any rotor group. It is offered to provide direction on how to avoid gross deficiencies or unattainable requirements.
