The variation of natural whirl speeds and instability of a rotating shaft subjected to end loads (i.e., axial compressive forces, moments, and torques) are studied. A finite element model of a Timoshenko beam is adopted to approximate the continuous shaft, and important factors such as the rotatory inertia, shear deformations, and gyroscopic moments are taken into account. The results show that the natural whirl speeds of the shaft do not always decrease when the loads increase and the types of system instability resulting from different end loads are not the same.
