Abstract

This paper presents rotordynamic modeling and performance analyses of a flywheel energy storage system rotor that utilizes a hybrid magnetic bearing having an energy storage capacity of 220 W h at its operating speed of 20,000rpm. A rotor model designed in solid works 13 and imported into ansys 14.5 is presented with some its main specification. Static structural analysis of the rotor has been performed using Ansys 14.5 in which the rotor model is made to undergo various analysis stages, total deformation, equivalent stress (Von- mises) and equivalent elastic strain. These results were examined and discussed, the maximum input torque for the rotor model was 4NM with the maximum total deformation occurring at 0.00002154mm along the rotor shaft, when the rotor speed exceeds its critical speeds, influences in the behavior of the gyroscopic effects on the system results in the rotor model experiencing various degree of deformations and mechanical failures.
