Abstract：A mechanical model and vibration control state equation of active vibration suppression technique based on smart spring for one rotating machine was established. The influence of the actuation forces of piezoelectric ceramic actuator, parameters of smart spring structure and speed influence coefficient of sliding friction force on the vibration suppression performance of smart spring mechanism was analyzed by numerical simulation. The simulation results show that, as the actuation forces increased, the vibration amplitude of system is decreased, and the vibration suppression performance is enhanced. There are two kinds of control technology for smart spring. One is stiffness control, and the other is damping control. The stiffness control can to be effective for vibration suppression under constant-speed and acceleration operation. The damping control has good effect only during the rotating machine is accelerating to traverse the critical speed, but it requires lower external voltage stimulus. The parameters of smart spring structure obviously affect the vibration suppression performance, so it is necessary for specific applications to reasonably select the parameters of the smart spring structure. The effect of speed influence coefficient on the vibration suppression performance is enhanced with the increase of the strength of system relative speed and the values of speed influence coefficient.
