摘要：
This paper is a contribution to the understanding of the generation and transmission of pressure ripples in hydraulic systems. Previous research on fluid-borne pressure fluctuations in hydraulic systems has been largely directed toward high pressure lines. This paper examines the behavior of the pressure fluctuations in axial piston and gear pump suction lines. It has been found that the unsteady flow taken in by a pump creates a standing wave n the inlet line in much the same way as a delivery line. The magnitudes of the pressure fluctuations are very sensitive to mean inlet pressure, due to changes in inlet flow ripple with mean pressure.
