The optimization design of a flywheel at present is based on material intensity only to maximize the speed of a composite flywheel, which is impropriety for an energy storage system since the speed of the rotor is also restricted by other factors. In this paper, an applied method for the structural design of composite flywheel rotor was developed. Considering restrictive factors, a computational model based on stress analysis was present, and the optimal interference and number of layers of the flywheel rotor consists of multiple rings were obtained. The optimal parameters could reduce the magnitude of stresses remarkably, especially the radial stress, by which the safety of the flywheel was improved and the design requirement would be satisfied.
