Investigating ANSYS Rotordynamics

Many have requested rotordynamics capabilities in ANSYS. Release 10.0 has capabilities that are of interest to many in this field. This paper will look into the Coriolis effects and how it can be applied in a finite element model. Also, gyroscopic effects will be discussed. A rotordynamics analysis will be performed to demonstrate the capabilities and limitations in Release 10.0 of ANSYS. Results will be compared to those obtained from in-house programs. A few textbook cases will be investigated as a baseline. This will gain confidence in utilizing the capabilities in commercial applications. A summary table of capabilities, limitations, and requests for improvements will be generated.
