Abstract: Based on the nonlinear theory, the unbalanced response behavior of the rotor
dynamic system supported by gas journal bearings is investigated. A time-dependent
mathematical model is established to describe the pressure distribution of gas journal bearing
with nonlinearity. The rigid Jeffcott rotor with self-acting gas journal bearing supports is modeled.
The differential transformation method is employed to solve the time-dependent Reynolds
equation of gas bearings. The unbalanced responses of the rotor system supported by finite
