Abstract: |
Complex rotating machine trains
especially trains including electric machines are subject to the most varied
and often most severe torsional disturbances. If
shaft or rotating component failures occur as a result of torsional
oscillations, the consequences can be catastrophic. In this paper a
comprehensive model and simulation method using analytical formulations are
developed to study both steady state and transient response of complex
rotating machine trains including several machines. Analytical results are
presented and recommendations for torsional
reliable trains are addressed. Couplings being the more accessible components
within the train are often modified to tune the overall system.
Recommendations for coupling are: High torsional
stiffness coupling (best and optimum option, if torsional
simulation confirmed frequency separation and transient torques) or flexible
coupling (more elasticity and damping and more maintenance) or integral rigid
forged flange connection (more rigidity, high natural frequencies and much
less damping). |
