Effectiveness of a ballast in flywheels made of composite materials

  • Published:
Mechanics of Composite Materials Aims and scope

Conclusions

  1. 1.

    Use of a ballast ensures a substantial increase of the energy capacity per volume of a flywheel only when the hoop of the flywheel is made of organoplastic, the maximum increase then reaching about 50%, while for glass-, carbon-, and boron-plastic this maximum increase is an insignificant 7–14%.

  2. 2.

    In the case of a ballast in the form of a ring fastened only to the hoop, with the ballast dimensions optimally selected, the maximum energy capacity of the flywheel depends only slightly on the ballast density.

  3. 3.

    In the case of a ballast in the form of a solid disk between hoop and shaft the maximum energy capacity per volume is attained when the hoop material and the ballast material have approximately equal densities, while the maximum energy capacity per mass will be attained by means of a ballast with minimum density.

  4. 4.

    The proposed method of analysis narrows down the range of search for the optimum relation between hoop and ballast dimensions.
