Abstract
It has been well known that the amplitude of pressure pulsation becomes extremely high when the frequency of the sorce flow pulsation coincides with the resonance frequency of the standing waves. Therefore pump rotational speed or length of a connecting pipe should be designed so as to avoid the resonant modes of the standing waves. The final aim of this reserch is to establish design tips for these parameters and clarify the standing wave characteristics in hydraulic circuits. In this paper, particulary, the influence of the termination characteristics of the circuits on the resonant mode of the standing waves is investigated both numerically and experimentarlly.
