Simulation and verification of an eccentric press system actuated by hyraulic-clutch-brake-combination controlled by a linear drive

This paper deals with a Matlab/Simulink-Simulation of an eccentric press with an hydraulic Clutch-Brake-Combination (CBC) and the verification on a standard moulding press. The outstanding characteristic of this system is the special control of the CBC. A servo converter controlled linear drive with an integrated hydraulic cylinder generates the pressure for the CBC. A developed pressure control is able to control the torque of the CBC and therefore the acceleration and deceleration of the powertrain. The simulation has been made to predict the behavior of the controlled CBC in an eccentric press. The simulation results are finally compared with the measurements at the real system.
