摘要： 针对飞轮储能系统升降速实验中极限转速为9300 r/min，小于飞轮储能的最高工作转速15000 r/min，这会大幅降低飞轮储能系统的最大储能量。为提高飞轮储能实验中极限转速，从结构设计角度出发，采用理论公式分析、SAMCEF Rotor有限元仿真分析并结合实验数据来研究盘式飞轮转子和柱式飞轮转子的临界转速分布规律及其稳定性。分析发现，质量相同、结构不同的盘式飞轮转子其二阶临界转速远远超过柱式飞轮转子，两者的一阶临界转速相同。根据不同工作转速和储能量要求的飞轮转子，采取不同的结构方案，确保其达到工作转速要求并稳定运行。

Abstract: For the flywheel energy storage system, the maximum speed of the flywheel energy storage system in experiments is 9300 r/min, which is less than the maximum rated speed of 15000 r/min. This will greatly reduce the maximum energy storage of the flywheel energy storage system. In order to improve rotor dynamics structural design, theoretical formulae analysis, finite element analysis of SAMCEF Rotor are used to study the critical speed distribution and stability of disc rotor and column flywheel rotor with combination of experimental data. The analysis result indicated that the second-order critical speed of the disc flywheel rotor with the same mass and different structure far exceeds the column-type flywheel rotor, and the first-order critical speed of the two types of flywheel is almost the same value. According to the different working speed and energy requirements of the flywheel rotor, different structural solutions should be adopted to ensure the requirements of the operating speed and stable operation.

Key words: flywheel energy storage, SAMCEF Rotor, critical speed, stability
