Abstract

Flywheel energy storage rotor generates strong centrifugal inertia force at high speed rotating state , and the centrifugal force causes the internal composite flywheel rotor stress. If the stress exceeds the ultimate strength of composite flywheel rotor, it will be destroyed.Using the double ring flywheel rotor design, it can offset a portion for high-speed rotation of the centrifugal stress because of the interference fit between the layers appear at the beginning of prestress, it also can be understood as the increased speed and flywheel storage flywheel energy storage system in a certain extent . Through the ANSYS stress analysis, the results showed that the radial stress produced by the double ring flywheel rotor is reduced by 11.706Mpa compared with the radial force produced by the single layer flywheel rotor, and radial stress is the key factor to restrict the promotion, so using the double ring flywheel rotor can improve flywheel speed and increase the flywheel energy storage?
