Research on Simulation and Control Strategy of Die-casting Machine Mold Opening Positioning System Based on AMESim
The die-casting positioning system is actually a control system based on meter-out switch valve.Due to the large inertia characteristic and the fluctuations in at different positions of.the system,The accuracy of the position would be low based on the conventional single-stage control.The mathematical model and AMES-im simulation model was estabilished.In view of the problem,a positioning control method based on multi-stage control method and a hydraulic system based on meter-out relief valve were designed.and tests it on the die-cast-ing machine's positioning system.Simulation results proved that comparing with the conventional single-stage control,the multi-stage control method based on meter-out relief valve has better dynamic performance.
