Abstract

A computer-animated graphical model visually conveys the movement and vibration of an entire shaft rotating within its bearings, and the behavior of the shaft at each individual bearing. The model aids a user in (1) visualizing an animated three-dimensional mode shape of a modeled shaft at high speeds, (2) visualizing the alignment state of the bearings of a modeled shaft at slower speeds, (3) visualizing the axial movement of a modeled shaft relative to a stationary component, and (4) visualizing the relationship between a rotating element, such as rotor, and a stationary element, such as a rotor housing, at locations other than the bearing locations. The model enables a user to compare shaft behavior at different operating conditions during a transient event, to see if a shaft is running at a proper position within its bearings, and to see if a shaft is contacting bearing surfaces or is dangerously close to such contact.
