Study on Dynamic Characteristic in Hydraulic System Based on Bypass Method by the AMESim

s. At present, based on the bypass method to measurement the dynamic of the high pressure side flow in hydraulic system became more and more. In order to analysis the dynamic characteristics, the bypass method measurement system flow schematic was introduced in this paper, the dynamic flow of the main oil and the system was obtained by using dynamic flow of the side oil. Meanwhile, the dynamic pressure of the main oil was obtained by using dynamic pressure of the side oil. From the results of numerical analysis indicates that it is feasible to use the bypass method to get the characteristics of the dynamic flow and dynamic pressure in the system.
