Abstract:
A bearing arrangement for a vibrating component including a bearing supported on a carrier for the vibrating component, comprising:a damper which interacts with the carrier, the damper including an inertial mass movable relative to the carrier, the damper further including a damper drive for moving the inertial mass;a drive circuit including at least one first sensing element for the vibrating component and a downstream signal generator, the downstream signal generator which generates two harmonic, out-of-phase first signals whose frequencies correspond to each other and to vibrations of the vibrating component, the downstream signal generator also generating a second signal, the second signal being supplied to characteristic curve elements whose output signals are multiplied by the first signals of the signal generator, thereby creating third signals, the third signals being added up in pairs and the resulting signals being multiplied by a fourth signal generated by a second sensing element to produce two fifth signals, the fourth signal being representative of the relative movements of the carrier, the two fifth signals each being supplied to a transfer element, the transfer elements producing sixth signals, the sixth signals each being multiplied by the first signals of the signal generator to produce seventh signals, the seventh signals being added to an eighth signal used to operate a damper drive, wherein frequency response compensation is provided which completely or partially compensates for changes in the force introduced into the carrier by the vibration damper, in particular due to the change in frequency of the vibration to be compensated.
