EXPERIMENT and SIMULATION on MAIN ALLOTTER'S ELECTRO-HYDRAULIC CONTROL SYSTEM of 50MN HYDRAULIC FORING PRESS

摘要

This paper introduce the main allotter's electro-hydraulic control system of 50mn hydraulic foring press, and model its mathematical model. Analyse response of the system with sine wave signal inputing, and get the result of that the dynamic response of the control system could be content with demand of the press working. And on electro-hydraulic control system of 50mn hydraulic foring press, the paper make an advanced analyse with the experimental data of water press which collect in field.
