In industry and transport technology, the flywheel in most cases is a rotating body with significant main moment of inertia [kgm2] compared
to the other parts of the mechanical system. Its first analogue has been known since ancient times as pottery’s wheel, wherethe sculptor of
clay drives his work table directly with foot or by means of elementary crank mechanism Figure1. During the first industrial revolution about
two hundred years ago, after the appearance of the steam engine, the flywheel was a vital element of it. Its initial purposewas to overcome
the so-called dead positions, and subsequently it carried out the energy transfer within a period of the stationary (steady state) motion to ensure a certain degree of non-uniformity of the angular velocity of the main shaft of the machine.
