Abstract In this paper, the turbine power simulator operates at a speed below its bending critical speed. However, the imbalance within the rotor generates vibrations, preventing the simulator from reaching its working speed. To address this issue, a dynamic balancing experimental study is conducted. Initially, low-speed balancing of the rotor is performed near the first-order critical speed. Subsequently, utilizing the dual-plane influence coefficient dynamic balancing technique, a high-speed dynamic balancing test of the rotor system is successfully carried out on the turbine power simulator test rig. After the field dynamic balancing test, the rotor’s vibration is significantly reduced, with a balancing efficiency exceeding 83% for all cases, demonstrating excellent vibrational characteristics and remarkable balancing effects. The research presented in this paper offers an effective approach for controlling the vibration of similar high-speed turbine power simulator rotors, thus holding considerable engineering application value.
