Design Of Pump Shaft Trains Having Variable-Speed Electric Motors
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1986)
With converter-fed variable speed electric motors, pulsating torques inevitably occur in the air gap and can cause torsional oscillation in the whole shaft line. The origin and behavior of these torques and how to calculate ...
Predicting And Improving The Dynamic Behavior Of Multistage High Performance Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1984)
Good rotordynamic behavior, implying sufficient stability margin and low sensitivity to unbalance forces, is mandatory for modern high pressure multistage pumps. Stiffness, damping and mass matrices describing the forces ...
