| Abstract: | A new kind of frequancy tracking damping vibration system with electromagnetic natural frequency controllable dynamic vibration absorber (NFCDVA) is presented in this paper. The system consits of sensor, frequency tracking controller, power amplifier and an electromagnetic NFCDVA. In this paper, the principle and characteristics of the absorber are described. The flow-chart graphs of the frequency tracking controller and experimental device are given. The frequency tracking and vibration damping experiments for vibration with varying frequency were carried out. The experimental results are satisfactory. |
