Vibration Analysis of Hollow Tapered Shaft Rotor

Abstract EN

Shafts or circular cross-section beams are important parts of rotating systems and their geometries play important role in rotor dynamics.

Hollow tapered shaft rotors with uniform thickness and uniform bore are considered.

Critical speeds or whirling frequency conditions are computed using transfer matrix method and then the results were compared using finite element method.

For particular shaft lengths and rotating speeds, response of the hollow tapered shaft-rotor system is determined for the establishment of dynamic characteristics.

Nonrotating conditions are also considered and results obtained are plotted.
