| Abstract: | By testing the hydraulic system of 200MN press, it is shown that the coupling vibration of power fluid and pipeline is the main vibration source of the system. The modeling of pump and pipeline system is established, the transfer matrices of fluid pipelines and related components are given the ways and means for the solution of characteristic impedance are proposed. It can be used for reference in the design of a hydraulic press system of high pressure and large flux. |
