Abstract

The invention discloses an energy storage flywheel and a design method thereof, and belongs to the technical field of energy storage flywheels. The energy storage flywheel comprises a hub and N layers of composite material rings which are assembled on the hub in an interference mode. The widths of the N layers of composite material rings are the same, and under the condition that the energy storage flywheel rotates, centrifugal force borne by all the layers of composite material rings is the same. According to the energy storage flywheel and the design method thereof, the defect that the radial stress does not meet the allowable strength requirement due to the increase of the radial stress ring by ring caused by centripetal force in the traditional multilayer equal-thickness layer ring design can be overcome, and the mechanical properties of various materials can be fully utilized, so that higher energy storage density can be obtained, and the design of a high-capacity and ultra-large-capacity composite material energy storage flywheel becomes possible.

Description

technical field [0001] The application belongs to the technical field of energy storage flywheels, and in particular relates to an energy storage flywheel and a design method thereof. Background technique [0002] At present, among many energy storage technologies, the flywheel energy storage system is highly valued and favored by the industry due to its outstanding advantages such as high efficiency, large capacity, fast response, flexibility, convenience, safety, reliability, and environmental protection. [0003] The energy storage density of an energy storage flywheel depends on the material used to make the flywheel. Among all the flywheel manufacturing options, although the energy storage density of the composite material is relatively high, with the continuous improvement of the capacity of the flywheel energy storage system, the mechanical properties of the composite flywheel It has approached the limit, and the current design theory and technical methods of composit...
