Development of Accumulator for High Frequency Ripple Absorption

概要

論文の詳細を見る
A new accumulator is developed which is possible to absorb ripples by pump and cavitation in valve, ranging from several hundred to several thousand c/sec in the hydraulic system. (Acc: abreviation of Accumulator) The attenuation of Acc in the case of constant flow source and constant pressure source when the pipe is terminated with a throttling load, was computed and compared with experimental values. Observation of the bladders of hat and belows type used in this experiment, was made and by life test, the endurance limit of them was investigated. By improving the bladder's profile and smoothing stress distribution, the author affirmed that this Acc had good endurance limit under ripple pressure of about ±15 kg/cm^2.
