Lateral and tilt whirl modes of flexibly mounted flywheel systems

Technical Report ·
OSTI ID:6432314
High performance, composite-material flywheel systems under current development for energy-storage purposes differ from turbine and compressor systems in that the flywheel rim is flexibly attached to the hub. Thus, for whirling with gyroscopic action, an axisymmetric flywheel system has four degrees of freedom, two associated with lateral translation and two with tilting. In the Sandia Livermore spin-test facility, the above system was driven by an air turbine which added two more degrees of freedom. An analysis of such a system is presented and applied to two versions of a specific design presently being developed.
