Summary:

A rotor-shaft system supported at one end by a spline coupling, and at the other end by a flexible bearing support having asymmetric and nonlinear characteristics is analyzed. The effects of nonlinearity and asymmetry in the flexible support, on the response to excitation from sliding friction in the spline coupling and rotor unbalance are investigated. The spline friction is represented as coulomb friction. As a result of the sliding friction excitation, a bounded nonsynchronous whirl is shown to occur at rotational speeds above the undamped natural frequency of the system
