Abstract

This work discusses performance analyses of a flywheel energy storage system rotor using ansys. Design of a rotor based on 3D modeling and simulation is presented, the flywheel theory is also studied. A basic static structure and modal analyzes were carried out to evaluate the performance of the model rotor under these condition and the results discussed. Rotor analysis is performed in which a rotor model designed in solid works is imported into the ansys 14.5 environment for the analysis to be performed. The rotor model undergoes various forms of vibrations and deformation analysis using ansys 14.5 software and the results examined and discussed. Increasing rotor rotational speed above its safe critical limits influences the behavior of the natural frequency due to higher gyroscopic and moments of inertia which will eventually results in the non-performance of the rotor thereby causing total deformation to the rotor model during its operational cycle.
