Direct Frequency Response Analysis
Frequency response analysis is an efficient method for
determining the steady state response of rotor bearing
system subjected to harmonic loading. The program
utilizes unsymmetric solver in complex frequency
domain using block assembly and block solver based
on Crout decomposition procedure.
THE INPUT INCLUDES:
- Frequency dependent harmonic imbalance forces due
to shaft or disc eccentricity or combination of both
Damped unbalance response F - Forward whirl, B - Backward whirl |

|
Whirl orbits at first two critical speeds |
|
THE OUTPUT INFORMATION INCLUDES:
- Amplitude output for displacements, velocities, and
accelerations.
- Orbits at user-defined locations for one excitation
period
- Phase spectra output for displacement, velocities,
accelerations
