Abstract: The influence of supplied pressure fluctuation on output accuracy
for the electro-hydraulic pressure control system of the rolling
mill is discussed. Based on the bond graph theory and
experimental study, the relationship between the variation of
system output pressure and the supplied pressure fluctuation and
the influence of the system bandwidth on system output pressure
are provided. A theoretical base for determining the allowable
fluctuation range of pressure and accurate design of constant
pressure source system is obtained.
Key words: Pressure
