The paper introduces basic methods of computational investigation for specific energy capacity of kinetic energy storages based on flywheel-housing scheme. In addition to the traditional estimation of energy capacity on the flywheel kinetic energy, we consider estimation of specific energy capacity of flywheel-housing system in potential field. We analyze the possibilities of the use of various structural materials in the manufacture of flywheel and its housing. Notice, that potential field in flywheel-housing system allows to increase the specific energy capacity of kinetic energy storage. 8126 D. V. Berezhnoi et al.

This paper focuses on strain-stress state of the flywheel in the kinetic energy storage. The flywheel kinetic storage is based on the flywheel-housing scheme in potential field, at the quasistatic increase of rotor velocity. It is particularly noteworthy that a potential field in flywheel-housing system allows to increase specific energy capacity of energy storage.
