| Abstract: | In view of the present phenomenon of serious pipeline vibration and loud noise while the locomotive piston air compressor working, the causation of the pipeline vibration is analyzed by calculating the natural frequency of the piping system, the natural frequency and the pressure pulsation of the gas column. Then, the measures such as the coordinate uses of absorption of vibration in buffer, shadow mask and reasonable structural support, are suggested. |
