Abstract


To improve labor productivity and free forging forgings dimensional accuracy , high speed forging hydraulic press came into being. In order to meet the needs of modern industrial development to be stable under the premise , and constantly improve the speed forging hydraulic press forging speed and accuracy of pressure . In this context , the superiority of the electro-hydraulic proportional speed forging hydraulic press is increasingly prominent, more and more widely . Characteristics of non-linear hydraulic control system for high speed forging hydraulic press , variable load disturbance , the control object is more complex and there is a large parameter variations , co-simulation technology, expand its dynamic and static characteristics Theoretical and experimental study has important theoretical significance and practical value. Speed ??forging hydraulic press 22 MN proportion as the basis, the use of dynamic analysis software ADAMS, modeling software Pro / E and system simulation software MATLAB / Simulink , the establishment of a co-simulation model 22 MN proportion of high speed forging hydraulic press , and the following aspects: first , to 22 mN speed forging hydraulic press entities as the research object to build and verify the correctness of the body three-dimensional model , the use of Pro / E and ADAMS . 22 MN high speed forging hydraulic press fast forging a key component of the system and loop modeling studies, the use of ADAMS / Control and Simulink data interface to build 22 MN high speed forging hydraulic press combined simulation model , and 22 mn fast forging speed forging hydraulic press system dynamic and static characteristics simulation and experimental studies . Third, the design of the single neuron PID and 22 mN speed forging hydraulic press fast forging system modeling and simulation studies , comparative analysis of simulation results with traditional PID control , and experimental verification . The results show that the single neuron PID has better control effect and enhance the robustness of the system while reducing adjustment time , allowing the system to show a certain self-adaptive , and is an excellent controller .
