Pressure pulsation dampers as a means of improving the inherent vibroacoustic charateristics of hydraulic test rigs

Abstract


The paper is devoted to the design and investigation of special dampers of working environment pressure pulsations intended to reduce the inherent hydrodynamic noise of test rigs. Structural designs of pressure pulsation dampers and the results of analyzing their efficiency in vibroacoustic tests of ship hydraulic system components are presented.
