Electric motors area commonly used as prime movers in reciprocating compressor applications. Dynamic torques generated by compressors are of concern. Motors and compressors are often connected through flexible disc couplings which provide minimal damping. Dynamic torques adversely affect motors as they are not built to absorb high torque variations. The response from reciprocating compressors is very unfavorable to the motor as a whole. When performed on drivelines, a torsional vibration analysis (TVA) can effectively predict shaft and coupling vibrations. However, this technique does not adequately predict the fatigue life of the rotor assembly attached/keyed to the motor shaft. Finite Element Analysis (FEA) in combination with TVA can be used to evaluate dynamic stresses in rotor assemblies and predict potential failures. Torsional responses predicted in the TVA are used as input forcing functions for the FEA. By using this hybrid analysis technique, modifications to the system can be made and verified prior to final manufacturing.
