Torsional Analysis Recip Compressors

[RPM38Super]

Does anyone have a good reference for describing the techniques or methodology used for a forced torsional vibration analysis of reciprocating compressor systems with motor drives. This would be to calculate the torsional amplitudes of vibration vs. frequency at the aux end of the compressor due to harmonic torsional loading at the compressor throws.

TIA

Don't have an answrr to your specific question, but thought I'd provide a link to our app. note on monitoring recipricating compressors as an FYI.
