Projects : Generator Rotor Retaining Ring Analyses

• 21 cases (projects) involving retaining rings
• Progressively increased the number of analyzed components
• Decreased analysis time from 700 hours to 400 hours
• Developed methodology for a standard ring modification

Models:

• ANSYS models for all existing components
• Contact areas were included

Analysis Goals:

• Predict low–cycle fatigue cracking
• Analyses to identify areas of existing high stress
• Conducted re-analyses to predict future performance of the modification – 3,000, 6,000 or 10,000 cycle design life is required
