Flywheel for energy storage

  1. May 26, 2015 #1
    Hello,

    I have to design a high inertia flywheel for energy storage. The flywheel must be something like in the drawing I attached. The question is: how can I calculate the Inertia and the stored kinetic energy in this type of flywheel?
    Can I consider it like a classic "Rim , hub and spokes" flywheel, thus considering it like if there was a continuous rim, and use the classic formulas found in literature, such as I_rim=m*R_m^2 (where R_m is the mean radius) for the inertia of the rim and E=1/2*I_r*w^2 for the kinetic energy stored?

    Thanks a lot for your help!

    Just curious?
    Why not use the Inertia calculations of said CAD program? It's much more precise than a mathematical assumption based formulation, as those intersections and fillets will have high error coefficients.
