Abstract A 200kW/180MJ flywheel energy storage system is designed to solve the problem of large load fluctuation of the power grid system. The finite element method is used to model and simulate the flywheel shafting, and the critical speed and vibration mode of the flywheel rotor are calculated, and the modal and harmonic responses of the flywheel rotor supported by mechanical bearings are analyzed. The full cycle detection of the flywheel speed rise and fall is carried out, the amplitude-frequency characteristics of the flywheel running process are recorded, and the amplitude-frequency characteristics of the flywheel are compared and analyzed. The flywheel energy storage system is running well without friction. The oscillation amplitude’s maximum analysis result is 1.6mm less than the designed gap of 3mm.
