英文摘要
      The exact simulation model of the body and the main control system of a large fast forging hydraulic press is built by using the ITI-SimulationX software. The integrated simulation of the three-dimensional body and the onedimensional system is performed. The results show that fast forging hydraulic press can attain the forging precision of ±1mm and the maximum forging frequency of 85 strokes/min during hot forging. For a large fast forging hydraulic press, which has wide process range and complicated operating conditions, we design the Takagi-Sugeno fuzzy controller which includes the forging stroke, forging penetration, maximum working pressure, working hydraulic cylinder number and the number of main pumps as input variables, and the open-close curve of the high-frequency-response proportional valve as output variable. Fuzzy reasoning rules are deduced from simulation results of the main control system by using MATLAB/Simulink software. The intelligent control for the main control system is realized by using the co-simulation interface modules of ITI-SimulationX and MATLAB/Simulink, providing high forging precision and fast response speed under different technological parameters and accommodating to various process requirements for large fast forging hydraulic press.
