摘要: This paper employs a hybrid numerical method combining the differential transformation and finite difference to study nonlinear dynamic behavior of flexible rotor supported by spherical aerodynamic journal bearing system. The analytical results reveal complex comprising periodic, sub-harmonic, quasi-periodic responses center center. Furthermore, changes which take place in system as mass rotational velocity are increased. proposed provides an effective means gaining insights into dynamics gas film rotor-bearing systems.
