Abstract: The rigid-body equations of motion for conservative rotating machine systems with position-dependent moments of inertia are found to reduce to a single, second-order, inhomogeneous, nonlinear, ...

Abstract: In this paper, the equations developed in a companion paper (Part I) are adapted for use in developing stability charts. The nonlinear equations of motion were developed for a two-degree-of-freedom ...

Abstract: An important question facing a designer is whether a certain machine system will have a stable operating condition. To date, the investigations which deal with this question have been scarce. ...
