Linear Transient Dynamic Analysis
Transient dynamic analysis determines the response of rotor
bearing systems to arbitrary time-varying loads. The program
utilizes Newmark-beta method for implicit direct time
integration using block assembly and block solver based on
Crout decomposition procedure.
THE INPUT INCLUDES:
- Damped / undamped whirl frequencies
Time history at inner rotor in one full period. Speed ratio=1.2 |
|
|
Whirl Orbit at inner rotor in one full period. Speed ratio=1.2 |
|
- Selective printout of mode shapes
- Nonzero initial conditions
- Time dependent concentrated loading
- Imbalance forces due to shaft or disc
eccentricity or combination of both
- Ground motion
THE OUTPUT INFORMATION INCLUDES:
- Time histories for displacements, velocities, accelerations
Time history at inner rotor in one full period. Speed ratio=1.3 |
|
|
Whirl Orbit at inner rotor in one full period. Speed ratio=1.3 |
|
- Shaft orbit time histories at user-defined locations
