โœฆ Synopsis

In this paper, transverse waves propagating in an infinitely long, rotating Timoshenko shaft subjected to axial forces are studied. The model includes the contributions of axial deformation to the transverse vibration of the rotating shaft. Four different types of wave motions, two cut-off frequencies and frequency spectra are defined and discussed. The effects of rotation speed, axial force and axial deformation on the frequency spectra, phase velocity and group velocity are examined. It is found that the wave motions are generally independent of the rotation speed and the axial load significantly affects the wave motions at small real wavenumbers.

In this paper, the wave reflection and transmission characteristics of an axially strained, rotating Timoshenko shaft under general support and boundary conditions, and with geometric discontinuities are examined. The static axial deformation due to an axial force is also included in the model. The
