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. |
