Abstract
Undesirable bending vibrations in at least one rotating component are reduced. An undesirable vibration is counteracted by the use of at least one actuator. A required sequence of signals to be applied to the actuator and/or an intensity level of those signals is based on an angle of rotation position of the rotating component. The rotating component is then subjected to a force based on the position of the angle of rotation.
Claims33
A method for reducing bending vibrations in at least one rotary cylinder of a processing machine including:
- providing at least one journal for said at least one rotating cylinder;
- supporting said at least one journal in a bearing;
- providing an actuator for exerting a bending stress for counteracting said bending vibration in said at least one rotating cylinder;
- engaging said journal with said actuator;
- determining an angle of rotation position of said at least one rotating cylinder;
- predicting a sequence of signals as a function of said angle of rotation position of said cylinder;
- and
- charging said actuator with said sequence of signals in a periodically repeating pattern.
