The calculation and experimental studies of vibration transmission through the pipeline compensators with liquid were carried out. No publications have been found among the scientific papers published on this issue. It has been demonstrated that the influence of structural resonances and the interaction of working medium pulsations with the structure increases vibration transmission through the compensator by two to three orders of magnitude or more with increasing frequency. The physical and mathematical models of this phenomenon are described, and a comparison of calculation and experiment is given. The ways of using the found interaction of medium pulsation and the structure to reduce vibration transmission by ten or more times within a certain frequency range are shown.
