The created version of SFC with a variable value of the feedback gain theoretically has the accuracy of operation of the “ideal” SFC when it is installed in forging and stamping equipment. A variable value of the gain is obtained by changing the pressure angle of the rolling element control device depending on the transmitted load. To obtain a variable value, the gain in the SFC was changed in the design of the control device. The experimental studies of the full-scale SFC sample with a variable gain, however, showed that the coupling does not have the accuracy of operation inherent in the “ideal” SFC. Since the gain was experimentally studied in the static loading mode on the installation with a shortened kinematic chain, i.e., with a smooth increase in the load (the time of the full overload, which leads to the operation of the SFC, is longer than the period of natural vibrations of the system), the effect of unaccounted dynamic loads is practically excluded.
