Abstract

A bearing arrangement for a vibrating component having a bearing supported on a carrier for the vibrating component and having a damper which interacts with the carrier and has an inertial mass that is movable relative to the carrier by a damper drive. The damper drive being provided with a drive circuit which includes at least one first sensing element of the vibrating component and a downstream signal generator which generates two harmonic, out-of-phase first signals, whose frequencies correspond to each other and to vibrations of a machine part, as well as a second signal characterizing this frequency. The second signal is supplied to characteristic curve elements whose output signals are multiplied by the first signals of the signal generator, and the third signals obtained in this manner are added up in pairs. The signals obtained in this manner each are multiplied by a fourth signal, generated by a second sensing element, characterizing the relative movements of the carrier. The two fifth signals obtained in this manner each are supplied to a transfer element. The sixth signals obtained in this manner each are multiplied by the first signals of the signal generator. The seventh signals obtained in this manner are added to an eighth signal that is used to operate the damper drive. A frequency response compensation is provided which completely or partially compensates for the amplitude and/or phase changes in the force introduced into the carrier by the inertial mass, in particular due to the change in frequency of the vibration to be compensated.
