| Abstract: | Accuracy and stability of phase measurement are essential requirements for high-speed dynamic balance of aeroengine rotor. In this paper, a vibration signal reconstruction technique is developed to ensure accuracy and stability of phase measurement under the condition of rotor speed instability. The experiment results show that the technique is suitable and effective in improving the phase measurement accuracy and stability. |
