Title:
ENERGY STORAGE FLYWHEEL AND DESIGN METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/204972
Kind Code:
A1
Abstract:
The present application belongs to the technical field of energy storage flywheels, and discloses an energy storage flywheel and a design method therefor. The energy storage flywheel comprises: a hub and N layers of composite material rings which are in interference fit on the hub. The widths of the N layers of composite material rings are the same, and when the energy storage flywheel rotates, the centrifugal force borne by all the layers of composite material rings is the same. Embodiments of the present application may overcome the defect of traditional multilayer equal-thickness layer ring designs that radial stress does not meet allowable strength requirements due to the increase of the radial stress ring by ring caused by centripetal force, and the mechanical properties of various materials may be fully utilized, so that higher energy storage density may be obtained, and the design of a high-capacity and ultra-large-capacity composite material energy storage flywheel becomes possible.
