✦ Synopsis

In their paper [1], Pennacchi and Vania use Eq. (1) as their starting point. This standard equation does not include geometrical deformations such as shaft bows. Consider a very low running speed without mass and damping forces and no external forces. In this case Eq. ( 1) predicts no vibrations. However, different axial positions of the shaft will still move in the radial direction. See e.g. [2] or [3].
