Mechanical And Hydralic System Co-Simulation And Energy Saving Character Research On 200kn Sine Pump Controling Forging Manipulator

As auxiliary equipment for forging presses, forging manipulator grips forging and mainly completes feeding, rotating, parallel lifting and other actions to coordinate with press or hammer .The use of forging manipulator can greatly improve the production efficiency, reduce energy consumption and increase utilization of forging materials. As a new technology, virtual prototype technology has important theoretical and practical significance to improve the hydraulic properties by conducting co-simulation and analyzing the forging manipulator mechanical and hydraulic system. The paper mainly study on the theory of 200 KN on sine pump-controlled forging manipulator hydraulic system.Based on virtual prototype technology, creat the mechanical and hydraulic model of 200KN on sine pump forging manipulator tong rotation and driving, implement data exchange between mechanical systems and hydraulic control system through data interface of AMESim and ADAMS. By co-simulation, we realize 200KN on sine pump forging manipulator driving and tong rotation under the control of hydraulic system.According to the principle and characteristics of the sine pump, a Micro-Electro-Hydraulic integration simulation model of tong rotation and driving position closed loop and flow rate compensation for position closed loop are established.The response characteristics of forging manipulator tong rotation and driving position closed loop and flow rate compensation for position closed loop are respectively studied, and also the energy-saving features and energy saving effect of flow compensation position control system was studied for sine pump.The effort produced by the system flow, pressure and load on the static and dynamic characteristics of the pump controlled motor system are studied.The results show that the tong rotation and driving hydraulic system flow rate compensation for position closed loop can use the one group PID parameters to relize different tong rotation angle and driving position response in different working conditions. At the same, the hydraulic system has the high energy efficiency during acceleration phase and the high energy recovery rate during deceleration phase.The higher value of hydraulic system flow rate and pressure, The faster response of tong rotation angle and driving position.
