Abstract

The mechanism is for damping mechanical vibrations in a system which incorporates a controlled drive and a positioning component connected mechanically via a flexible unit incorporating a torque or power transmitter. A correction block is formed as the series connection of a differential unit, a unit for setting up a lag and a unit for amplitude balance connected to the torque or power transmitter and the controlled drive. A signal at the drive input is produced which has the opposite phase to the exchange component of the signal corresponding to the measured torque or power.
