Abstract: In a method and a device for actively suppressing pressure oscillations or pressure pulses in a hydraulic system of a cold or warm roll train or a strip treatment installation, the following method steps are carried out: a) detection of a pressure signal by means of a pressure sensor by permanent measurement of a pressure in the hydraulic system; b) determination of an alternating component of the pressure signal; c) determination of at least one temporally changing actuating variable in real time with the aid of a regulator, taking at least one setpoint value and the alternating component into consideration; d) loading of at least one actuator with the actuating variable, the actuator changing a volume which corresponds to the actuating variable and is connected to the hydraulic system, as a result of which the pressure oscillations in the hydraulic system are suppressed.

Abstract: A method and an apparatus for semiactive reduction of pressure oscillations in a hydraulic system of a cold or hot rolling mill or strip handling installation for iron, steel or aluminum materials has the following method steps in the stated sequence:a) detection of a pressure signal by a pressure sensor by permanent measurement of a pressure in the hydraulic system; b) determination of an alternating component of the pressure signal; c) determination of at least one manipulated variable, which varies over time, in real time with the aid of a regulator, taking account of the alternating component; d) application of the manipulated variable to at least one actuator, with the actuator changing a natural frequency of an oscillation damper which is connected to the hydraulic system, and thus reducing an amplitude of the pressure oscillations in the hydraulic system.

Abstract: A method and an apparatus for suppression of oscillations in a rolling installation is described. By means of a hydraulic roller engagement third-octave oscillations are effectively suppressed, thus making it possible to improve the quality of the rolled material and/or the productivity of the rolling installation.

At least a portion of the frequency response at frequencies f≧80 Hz has a magnitude drop of ≦3 dB, and the phase lag φ in this frequency range satisfies the conditions f≧19·{square root over (φ)}+3.1·10−6·φ4 and φ
