Abstract: With the mass limited, the dynamic stability of its system insured, volumetric energy density consided as the figure of merit, the inertial type of energy accumulator of the high speed flywheel is optimized using the Lagrange factor method and the finite element method is employed to carry out the numerical analysis of stresses within the flywheel in practically steady and unsteady states, so the effective way to its rational design and analysis, reliable insurance for utility safety are provided.

Key words: Energy storage flywheel, Finite element analysis, Optimized design
