Rotordynamic Analysis

Case histories include:

• Over 40 cycles of lateral and torsional rotordynamic analyses for the LM5000 engine/integrated assembly loads and vibrations predictions involving nominal rotor unbalance, blade-out contingencies, and torsional cases. Design/analysis of an isolated mounting system and comparison of analysis to field data measurements.
• Multiple cycles of lateral and torsional rotordynamic analyses for the LM6000 engine/integrated assembly loads and vibrations predictions involving nominal rotor unbalance, blade-out contingencies, transient startup, shutdown, short circuit, and malsynchronization. Modeling of and loads/vibrations predictions at the generator hydrodynamic bearings.
