Active control of gear vibration using specially configured sensors and actuators
No full textThis paper describes an active control system for reducing the vibration of a pair of meshing gears caused by the variation of meshing stiffness. A gear meshing model is developed and used to determine the magnitude of the secondary force required to cancel gear vibration and this is shown to be related to the modulation index of meshing stiffness. Possible configurations of actuators and sensors to implement the control scheme are proposed and some experimental results are presented
