Static Analysis of a Flywheel under Constant Angular Velocity
.. Preprocessing via Altair Hypermesh (Part 1)
.. Solution via MD Nastran (Part 2)
.. Postprocessing via Altair Hyperview (Part 3)

Overall Dimensions
.. 175 [mm] Outer Diameter
.. 20 [mm] Inner Diameter
.. Inner section holes, 8 equally spaced, D=8 [mm]
.. Mid section holes, 4 equally spaced, D=15 [mm]
.. Outer section holes, 8 equally spaced, D=10 [mm]
.. Symmetric extruded cuts and variable thickness
Material
.. AISI 316 Stainless Steel
Loading
.. 6000 [rpm] (628 [rad/sec]) angular velocity around neutral axis
BC and FE Model
.. Inner surface (contact surface with rotary shaft) is fixed
.. No separation between the flywheel and the shaft
.. Rest is free to move and rotate
.. Meshed with 2nd order CTETRA elements
