2011 International Conference on Electronic Mechanical Engineering and Information Technology Analysis of Voltage Source Control Characteristics of Clearance Control Magnetic Dynamic Absorber B o SONG a , Huimi n FENG b , Chuanguan g DING C School of Mechanical Engineering University of Jinan Jinan, Shandong , 250022 , China email: a. me_songb@ ; b . fhminl23@163.com ; c. ujnding02@163.com Abstract—Some problems existing in the traditional absorber adjustment and can absorb vibration in a relatively wide can be solved better by adopting clearance control magnetic frequency range which provide a new vibration control dynamic absorber to control the imbalance vibration of rotors . components for the rotor . It can control the imbalance For the special structure of conical electromagnet, stiffness and vibration of the rotor in a relatively wide frequency range . In damping equations of the electromagnetic dynamic absorber the specific process of the application and installation, it can are derived when voltage source is taken as the power of the be directly mounted on the rotor ends less restricted by electromagnet, and the influence law of various parameters on installation space and not have an greater effect on the the stiffness and damping characteristic of the clearance
