Compensating mechanical vibrations involves superimposing discrete frequency component(s) of vibration with harmonic torque of equal frequency, defined amplitude/phase

摘要

The method involves superimposing at least one of the discrete frequency components of the mechanical vibration (2) with an essentially harmonic torque (14) of equal frequency with a defined amplitude and phase by an actuator (11) and independently of the other frequency components so that the vibration amplitude at this frequency is reduced. Independent claims are also included for the following: a group of printing mechanisms and a printing machine.
