A novel transient high-speed flexible rotor balancing method is derived and the transient run-up response information based balance method is used to balance a power turbine rotor of turboshaft engine. The balance efficiency is studied systematically to prove its robustness under two disturbance factors, i.e., random disturbed rotating speed and noise polluted vibration signal. Results show that the transient balance method can achieve satisfactory balance efficiency on real rotors. The disturbances have influence on the identification accuracy of the equivalent unbalance, but the robustness is good on most cases and it is a suitable technology for real applications.
Key words: transient balance technology / turbine rotor / robustness / balance efficiency
