A modal-based balancing method for a high-speed rotor without trial weights

Yun Zhang et al.

Summary: A modal-based balancing method without trial weights is proposed for high-speed rotors to effectively suppress unbalance-induced vibration, ensuring smooth and safe operation of the rotor at high speeds. Numerical simulation and experimental results validate the proposed method, showing successful suppression of unbalance-induced vibration.
