Webflywheel based on the calculated mass moment of inertia and material properties. This will be covered in another article. Design steps and formulas Step-1: Coefficient of fluctuation calculation Input required: Maximum and minimum speed Flywheel inertia/size depends upon the fluctuations in speed. The difference between maximum & minimum WebProperties of several composite materials suitable for flywheel energy storage were investigated. Design and stress analysis were used to determine for each material, the maximum energy densities and shape factor of the flywheel. The materials identified based on the results from this study outperformed the boron/epoxy–graphite/epoxy combination.
WebFirst, determine the expression for the energy of a rotational system. Our flywheel will be a hollow cylinder, which gives us Mr 2 for moment of inertia. E-energy. I-inertia. M-mass. r-radius. w-angular velocity.
