Abstract:The skywheel's stability analysis is to ensure the stability of it in the normal
 operation and the limit states. The rim's stability analysis and the whole stability analysis are considered. The stability calculation has three parts, including static calculation, linear buckling analysis and geometrical nonlinear stability analysis. The ANSYS software is used to analyze the stability of the skywheel.
Keywords:skyscraper wheel structure； stability analysis； geometrical nonlinearity； stability coefficient
