Abstract:

For the problems of pressure relief impact of large die-forging,the hydraulic system, pressure relief loop and its principle of 4000t die-forging hydraulic press were analyzed .The mathematical model of pressure relief system was established and the modle was simulated with the Matlab/Simulink.The simulation results and experimental results were compared and analyzed,which verifies the accuracy of the model.Using the model,the influence and law of the spring`s elastic stiffness , the oil elastic modulus and input voltage to pressure relief effect were analyzed,which provides a reference to the pressure relief loop optimization design and the processing technology design of the large-scale die forging machine.
