“…For flywheels of arbitrary shape, numerical methods for studying the specific kinetic energy are proposed in the literature [1][2][3][4][5][6][7][8][9]. In a number of works kinetic energy storage devices made of rubber-like materials are proposed, for the calculation of which special methods are proposed [10][11][12][13][14].…”

Abstract. In this paper, the specific energy intensity of the kinetic energy storage devices, including the flywheel-casing scheme in the potential field, is investigated. The possibilities of using various structural materials in the manufacture of structural elements of a mechanical accumulator are analyzed, the stressstrain state of the flywheel and the casing under quasistatic increase in the rotational speed of the rotor part of the structure is investigated. It is noted that the presence of a potential field in the flywheel-casing system makes it possible to increase the specific energy intensity of the kinetic energy storage.

“…The main limitation in implementing such a technology is the rotational speed of the rotor part of the kinetic storage, which can lead to an increase in the stress level and its possible further destruction. In the literature, we give some estimates of the specific kinetic energy of rotation of the flywheels of the canonical form [1][2][3][4][5][6][7][8][9]. For flywheels of arbitrary shape, numerical methods for investigating the specific kinetic energy are proposed in the literature.…”

Abstract. In the work for different cases of nozzles of layers of the super-magnetic pendulum, exact solutions in the stresses are obtained, and estimates of the increase in its specific energy are given. Dependences of tensile stresses in a tape are obtained when winding it into a superflywheel, an increase in the specific kinetic energy in the super flywheel is observed with a decrease in the relative radius of the inner hole.

“…With the development of the latest technologies in power and transport industry the problem of energy storage becomes crucial. One of the rapidly developing areas in energy storage and energy transformation is the development of new schemes of kinetic energy storage devices [1][2][3]. Furthermore, to reduce the aerodynamic losses, which are the result of high angular rate of the principal part of kinetic storageflywheel, a strong body (which is a vacuum chamber) is used.…”
