Experimental study of the stress-strain state and load-carrying capacity of models of power-plant flywheels made of composite materials

Abstract

1. The use of a design In the form of a thin additional ring on the rim of a disk flywheel (type II) lowers the load-carrying capacity of the latter. 2. The use of a perforated disk (type IV) as a flywheel to reduce or equalize the stresses is inexpedient, since the stored kinetic energy is reduced more than the stresses. Theoretical determination of the actual stress-strain state of shaped disks made of anisotropic material requires the use of methods which consider the effect of axial anisotropy. 3. Henceforth in designing energy storage devices, a disk flywheel of type V should be considered to have promise.
