Abstract
The vibration caused by unbalance of the rotor system is especially strong at critical speed. To reduce the rotor vibration and increased system stability, many domestic and foreign research scholars of the rotor vibration mode of vibration control at present, Based on the understanding of the various modes of vibration foundation, established the goal of this research and research methodologies : Application engineering background, combined rotor dynamics theory, electromagnetic theory and data acquisition technology, For passive electromagnetic damper eliminate vibration of the pilot study.
Based on the current domestic and foreign scholars research work on the rotor vibration control, the various control methods and comparison of several existing actuators in the form of structure and performance summary. Procedures for rotor vibration signal acquisition, on the origin used for Collecting vibration signal data analysis and comparison. Research passive electromagnetic vibration damper augmentation effect, and through experiments demonstrate the passive electromagnetic damper damping effect. On this basis, and the passive electromagnetic damper for the single-disk rotor vibration control system of experimental research further, with the experimental data and the curve of the spectrum of the experimental system to be effective and reliability test.
Keywords: passive electromagnetic damper, rotor system, damping coefficient, experimental study
