Pump Tut - WHY MACHINES FAIL TO FOLLOW TEXTBOOK STATED RULES, AS ILLUSTRATED BY SHAFT CRACK AND ROTOR SELF EXCITED VIBRATION CASES IN CRITICAL MACHINERY
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
This tutorial demonstrates some aspects of rotating machinery diagnostics where there is an apparent difference between the actual response of a machine and its expected behavior for a certain type of malfunction as typically ...
Self excited torsional vibration in single shaft combined cycle turbine-generator train
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
This case history describes the investigation of the source of unstable behavior of a newly commissioned single-shaft, combined cycle, power generator unit. The source was found to be nonlinear operation of the flexible ...
