Vibration Reduction of Pump and Piping System

In this paper, Firstly, it is shown that the bending mode vibration of check valve is comparatively large because resonance. Secondly in order to decrese the bending mode vibration of check valve, some practical dynamic vibration absorber have been developed and its effectiveness is investigated as installing it at the check valve of piping system practically.
