Pilot Study of Dynamic Simulation on Hydraulic Supply System of HAGC

抄録

The hydraulic automatic gauge control (HAGC) system is the core of the automatic gauge control system in a high speed strip mill. A ripple of the servo valve power supply may affect the performances of HAGC. From the characteristics of the servo valve power supply for a HAGC system, the static relationships of the accumulator's parameters and the power supply, which equips pressure compensated variable displacement pump, are analyzed. By the power supply system modeling and simulation, with the help of the software EASYS, the useful results have been obtained as follow: 1. the relationship of the rate of pressure ripple and the accumulator; 2. the adequate volume of an accumulator; 3. the oil pipe's parameters and the optimal position of an accumulator; 4. the diminution of the load effect in actuator.
