Abstract

The vibrational behaviour of a rotating beam oriented perpendicular to the axis of spin has been investigated for all possible combinations of free, clamped, hinged and guided boundaries. The fundamental frequency of the beam in the plane of rotation and that perpendicular to it has been determined by assuming in most cases trinomials for the basic deflection mode. The effects of the speed of spin, the hub radius and aspect ratio of the beam have been investigated and exhibit in many cases pronounced influence upon the natural frequency and buckling.
