Torsional rotor dynamics - Distribution of inertia and stiffness

Figure 43 shows the shaft line of a compressor unit consisting of a 430 kW electric motor M, a high-speed coupling A _GV with moment of inertia I _GV , a gear reducer R, a low-speed coupling A _PV with moment of inertia I _PV , a flywheel V and a two-cylinder air compressor C. The motor runs at average speed N _E0 = 1487 rpm, and the compressor at speed N _S0 = – 425 rpm. The internal transmission of the...
