Flywheel Rotor

Flywheel rotor is the very important component in the flywheel energy storage system (FESS). The key factors of rotor, such as rotor materials, geometry and fabrication process, have directly influence on the performance of FESS. At present, press-assembling the rotor with shrink-fit is used usually to increase strength of composite flywheel rotors filament wound in the radial direction. This paper is concerned that the Von Mises equivalent stress distribution of the metal hub and the radial stress distribution of the composite rim at the speed of 20000rpm by the 3D finite element method. The materials and corresponding minimum value of interference fit of the flywheel rotor are determined based on the analysis results.

Flywheel Rotor

In order to improve the radial strength of energy storage flywheel, this paper design and analyses the multi-ring flywheel rotor in different conditions by finite element method. From the results, we can confirm that interference condition is critical influence on the stress gradient of the rim. The results can provide a guide for high energy density multi-ring composite flywheel rotor design.

Flywheel Rotor

The combination of composite rotor and mounting shaft is mainly realized by press fit. In the paper, the initial stress distribution of interference fit between composite rotor and mounting shaft, the centrifugal stress due to high speed rotation are studied systematically. Based on the principles of material failure and detachment constraint at high speed rotation, a calculation method for the appropriate interference is proposed. Finally, specific example is analyzed to verify the feasibility of this method.
