The reciprocation hydrogen compress has pulsation which is happen noise and vibration. Noise and vibration that happen by pulsation have bed effect machine and working environment. So, must know vibration special quality of compress to decrease these noise and vibration, executed analysis using nastran that is common use program. Find and compared each mode shape when consider Crank case analysis and consider Crank case and cylinder together through free vibration. And to search rejoinder about shock by Crank easel s pulsation 0 ~ 100 ㎐ because do sweep forced oscillation analysis achieve.

A few intake stations have vibration problems caused by pumps, motors and pipes. The vibration transferred from pumps, motors and pipes excites building severely. Therefore, the crack is generated on building wall and people who work at intake station are damaged. In this paper, the vibration and noise have been measured and analyzed for pumps, motors, pipes and building at intake station. Also, the cause of vibration and noise is identified. Finally, the reference of vibration and noise is established using results of measurement.
