Torsional Vibration - Pump or Diesel?

Torsional Vibration - Pump or Diesel?

Torsional Vibration - Pump or Diesel?

(OP)
I'll post in both Dredge and Pump Eng to get everyone's expertise.
Looking at the shaft torsional vibration in a dredge pump, direct driven with a low rpm diesel thru a mechanical clutch.
Assuming that Vane Pass contributes to the torsional signal, what percent of total or mean torsional value should this be considered as for First order and Second order harmonics?
Thanks folks!
