摘　　要：飞轮转子系统的结构布局对其高速旋转的稳定性有至关重要影响,以600Wh飞轮储能转子系统作为研究对象,通过建模及理论分析得到了转动惯量比与旋转运动稳定性之间存在的关系,采用转子动力学专业分析软件SAMCEF Rotor分析了两种不同转动惯量比转子的涡动频率振型,临界转速等。有限元分析结果和理论建模分析结果互为验证,结果表明:当转动惯量比接近1时,对工作转速超过一阶临界转速的飞轮转子系统,转动惯量比小于1时稳定性较转动惯量比大于1时更有优势,研究结果对以后大容量飞轮储能转子系统结构设计有重要参考依据。The structure of the flywheel rotor system is very important to the stability of the high-speed rotation. With the 600 Wh flywheel energy storage rotor system as the research object,the existence of the inertia ratio and the rotational motion stability is obtained by modeling and theoretical analysis. The eddy frequency and the critical speed of two different moment of inertia models are compared and analyzed by SAMCEF Rotor. Finite element analysis and theoretical modeling analysis results verify each other. The results show that when the moment of inertia ratio approaches 1,the stability of the flywheel rotor system whose operating speed exceeds the first order critical speed is better than that when the moment of inertia ratio is less than 1,which has important reference on the structure design of large-capacity flywheel energy storage rotor system in the future.
