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.
Types of Mechanical
System Vibration Analyses
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
