Technical Field

[0002] Composite material flywheel rotors have been widely used in aerospace, new energy vehicles, and other fields due to their high specific strength and high energy density. Research on failure analysis and strength prediction of composite material flywheel rotors involves analyzing various mechanical failures that may occur during their use and predicting their strength at failure based on complex stress conditions and fracture modes. Currently, the damage and failure mechanisms of composite material flywheel rotation systems have been extensively studied, involving different material combinations and manufacturing technologies. At the material level, the failure mechanisms and strength prediction of composite materials are influenced by many factors, including the properties of the fiber and matrix materials, the laminate structure, and the regional stress state.

[0003] Traditional composite material flywheel rotor analysis devices cannot monitor flywheel rotors of different specifications, thus reducing the practicality of monitoring during use. Furthermore, they may face multiple failure modes during high-speed operation. Although some studies have explored the failure mechanism through numerical simulation and other methods, there is a lack of experimental equipment that can comprehensively and accurately simulate actual working conditions and analyze the failure process. Therefore, an experimental device for failure mechanism analysis of composite material flywheel rotors is needed to improve the above-mentioned problems. Utility Model Content
