Abstract

A method for absorbing torsional vibrations of a printing machine, wherein at least one torsional vibration-absorbing element acts upon a gearwheel train of the printing machine, includes determining a first characteristic form and characteristic frequency of a printing machine, and assigning to at least one shaft journal of a gearwheel whereon highest amplitudes of the first characteristic frequency occur, a passive torsional vibration absorber modulated to reductions of the first characteristic frequency; and a device for performing the method.
