Simulation Analysis in Cylinder Hydraulic Synchronous Control System of Main Drive System of Heavy Forging Hydraulic Press

Abstract

An overly large passive synchronization system will be needed in a Heavy forging hydraulic press while entirely relying on passive compensation. And it will increase developing and maintain costs of the equipment. Therefore the main drive system should be considered. The paper developed mathematical model of the cylinder of the main drive system from the perspective of the main drive system of the heavy forging hydraulic press; the eccentric load points, load size and speed of moving beam are the three major factors that influence the synchronization of cylinders. Synchronous Controller was linked in the active corrective procedures and simulated based on Simulink, simulating results show that the eccentric load points have the biggest influence on the cylinder synchronization, while the speed produces smaller effect.
