| Summary: | For many years transfer matrices have been used to evaluate
the steady-state vibration response of linear rotor bearing
systems. More recently, they have been used to evaluate
the steady-state periodic vibration response of nonlinear
rotor bearing systems. For quasi-periodic and chaotic response,
a transient solution is mandated and transient solution
software can also be gainfully used to evaluate the
stability of the above-mentioned periodic solutions. To date,
transient solutions generally necessitate a different lumped
parameter discretization of the rotor and involve solving simultaneously
the differential equations for every degree of
freedom. This article shows how transient analysis can be
performed while maintaining the transfer matrix lumped
parameter discretization. The technique is illustrated for a
non symmetric unbalanced flexible rotor supported on hydrodynamic
journal bearings or deep-groove ball bearings. |
