초록

The reciprocating type hydrogen compressor is occurred by the pulsation from the mechanism and this pulsation is make much noise and vibration. Therefor snubber is installed for pulsation decreasing. The five type snubber models were designed for increasing pulsation amplitude reduction and decreasing pressure loss in snubber considering output pipe location as design value. And the pressure flued analysis is carried by CFD. In this paper, each type snubber according CFD result are analyzed by the MSC/NASTRAN to identify the vibration characteristic of each type. The vibration results are compared with CFD results.
