Abstract

The invention relates to a method for reducing the vibrations occurring in a hydraulic system (1) and to an arrangement for carrying out the method, in which method the occurring vibrations are determined, and the occurring vibrations are superimposed through targeted actuation of certain components (5) of the hydraulic system, such that the occurring externally excited vibrations are reduced.
