Therefore, the selection of appropriate rotor materials and the design of rotor structure are the key to reducing the cost of flywheel energy storage, which is crucial for the promotion of flywheel energy storage. Several review papers address different aspects of FESS research.
Among them, the rupture of the flywheel rotor is undoubtedly the most destructive flywheel energy storage system failure. Therefore, in the design process of flywheel rotor, it is necessary to fully evaluate the operation safety of flywheel energy storage system based on the material, size, and speed of the rotor.
Different flywheel structures have important effects on mass distribution, moment of inertia, structural stress and energy storage density. Under a certain mass, arranging the materials as far away as possible from the center of the shaft can effectively improve the energy storage density of the flywheel rotor per unit mass.
Arvin et al. used simulated annealing method to optimize the structure of composite flywheel and optimized the energy storage density of flywheel energy storage system by changing the number of flywheel layers.
In the future, the focus should be on how to improve the stability of the flywheel energy storage single machine operation and optimize the control strategy of the flywheel array. The design of composite rotors mainly optimizes the operating speed, the number of composite material wheels, and the selection of rotor materials.
This paper describes a two-part study of depleted uranium alloys: First, the mechanical behavior of DU alloys was determined in order to extend the limited set of mechanical properties reported in the literature (Eckelmeyer, 1991). The mechanical properties measured include the tensile behavior the impact energy.
