Coupled Bending-torsional Vibration Analysis of Rotor System with Two Asymmetric Disks
The dynamic equations derived based on the actual rotor system with two asymmetric disks. In the analysis, the eccentric, rubbing fault characteristics and internal damping effects is considered, and all the analysis is established based on nonlinear oil film force model and coupled bending-torsional differential equations. The RuggeKutta method is used to solve numerical model, the torsional displacementresponse, torsion angle and Poincare map are obtained. The results show torsion amplitudes with initial phase difference π/2 is larger than initial phase difference of π and 0. In order to eliminate the rigid rolling component the relative torsional angle must be considered.
