SwRI: Mechanical Piping Vibration Analysis: Compressor System and Pump System Analyses:

Mechanical modeling techniques are used to eliminate excessive vibration and dynamic stress caused by mechanical and pulsation-induced shaking forces generated by compressors and pumps. Mechanical analyses are performed to assess the likelihood of a coincidence of system component structural resonance and acoustic (pulsation) energy within the piping system. The extent of a mechanical system vibration analysis can vary:

• Basic review of piping restraint types and locations

• Detailed modeling of the compressor manifold piping system

• Calculation of dynamic stress and vibration amplitudes of system components and piping
