| Abstract: | The influence of supplied oil pressurefluctuation on output accuracy for the bendingroll electrohydraulic servo control system ofrolling mills is duscussed and the system dynam-ic characteristics is improved by the dynamicpressure feedback network through the experi-mental study and computer simulation. The rela-tionships between the output pressure of hy-draulic control system,the bandwidth of the sys-tem and the fluctuant supply oil pressure aregained. The dynamic pressure feedback networkis a reliable and efficient correction method forthe system. Therefore theoretical base for deter-miniing the allowable fluctuation range of pres-sure and accurate design of constant pressuresource system are also obtained. |
