摘要： The invention relates to a method for compensating deviations in a deforming operation between two beams of a press, comprising of arranging one or more compensating element at a suitably chosen location in the press, detecting the deviations and moving the compensating element(s) relative to the beams by (electro) mechanical means during the deforming operation such that the detected deviations are compensated. The compensating elements can be moved here to an over-compensating position prior to the deforming operation and pressed out of their over-compensating position during the operation by the load on the beam, wherein each compensating element exerts an adjustable resistance force on surrounding parts of the press. It is conversely possible for the compensating elements each to be pressed stepwise to a position compensating the detected deviations during the deforming operation. It is possible to use (piezoelectric) actuators to exert the resistance force and/or to move the compensating elements. The invention further relates to a device with which this compensation method can be performed.

摘要： Vibrational movement between the top of a lens and a main plate on which the lens is mounted is reduced by attaching between the lens and the main plate a lens support which detects relative movement between the lens and the main plates using piezoelectric sensors and compensates for that movement to reduce vibration using piezoelectric actuators which are in series with the piezoelectric sensors. The control signal which is generated to actuate the actuated piezoelectrics is generated by a controller.
