| Abstract: | The range of interference required by the rotor sheath of high-speed energy storage flywheel is calculated by analytic method. The stress analysis of the sheath in static state and working state is carried out by finite element software. The simulation results are in good agreement with the analytical results, and the validity of the results is verified. The thermal deformation caused by the heating for the sheath during the assembly process is analyzed, which provides the basis for the interference fit of the sheath. Finally, the model of flywheel rotor is simulated and tested, and the error of simulation and experiment is 0.6 %. |
