A flexible rotating beam is modelled using Timoshenko beam theory and a non-inertial reference frame that leads to a pseudo-pinned-pinned formulation. The frequency equation and orthogonality conditions are derived and compared with those for the pseudo-pinned and pseudo-clamped formulations. A finite dimensional model is presented and is used to derive the transformations between the three formulations.
