Tvarová optimalizace rotoru setrvačníku

Abstract

This thesis focuses on the shape optimization of a flywheel rotor, which forms part of a flywheel energy storage system. The introductory section provides a literature review on energy storage using flywheels. This is followed by a structural analysis of the rotor. The rotor’s shape is then optimized with the aim of increasing its mass moment of inertia. Cavities were incorporated into the optimized geometry to accommodate inserts made from a tungsten- uranium pseudo-alloy, further enhancing the mass moment of inertia and the amount of stored energy. In the final part of the thesis, the dynamic response measured on a manufactured prototype of the flywheel energy storage system is evaluated. The obtained results are analysed, and the conclusions are presented.
