Identification in the Frequency Domain of Mechanically Coupled Axes on Servo-Screw Presses

Abstract

The article deals with the system identification of drive trains on forming machines. The aim is to analyze the mechanical properties in the frequency domain. A comparison of uncoupled single axes with several axes in a coupling system should provide information on whether different controller parameters or controller structures have to be adapted for both cases. This will be investigated using the example of an electromechanical die cushion on a servo screw press.
