In general, the flywheel should first satisfy the requirement of energy storage capacity. The rotor of flywheel provides most of the kinetic energy. Excluding the energy stored in the shaft, the kinetic energy storage E k in a rotating flywheel rotor is given as, where I is the rotational inertia,. .
As described previously, the problem is to find the optimal shape of flywheel with the objective maximizing energy density under the constraints of allowable. .
It is easy to understand that the allowable stress constraint will affect the shape design of flywheel. As a result, both the optimal shape and the maximum energy. [pdf]
