摘要

摘要: 以600 Wh飞轮储能系统为研究对象，为计算飞轮转子系统的临界转速分布及评估在高转速下运动稳定性，采用SolidWorks进行三维建模并导入有限元软件SAMCEF Rotor求解其临界转速和模态振型。对飞轮储能系统进行升降速试验采集动态试验数据并通过时域图、频域图、轴心轨迹图进行分析。将有限元分析与试验数据进行对比，结果表明：飞轮转子系统在临界转速时振幅明显大于稳定转速时，在工作转速中，轴心轨迹重复性较好，没有超过气隙值0.3 mm，稳定性良好，为不同储能飞轮转子的改善和设计提供参考和依据。

Abstract: Taking the 600 Wh flywheel energy storage system as the research object, in order to calculate the critical rotational speed distribution of the flywheel rotor system and evaluate the stability of the movement at high rotational speed, the SolidWorks was used for 3D modeling and the finite element software SAMCEF Rotor was used to solve the critical rotational speeds and vibration modes. The dynamic experimental data of the flywheel energy storage system were collected and analyzed by the time domain diagram, frequency domain diagram and axial orbit diagram. Comparing the finite element analysis with the experimental data, the results show that the vibration amplitude of the flywheel rotor system at the critical speed is significantly greater than the steady speed; in the working speed, the recurrence of the axial trajectory is good, and it does not exceed the air gap value of 0.3 mm indicating good stability performance, which also provides reference and basis for the future improvement and design of different energy storage flywheel rotors.
