| 摘 要： | 大功率高储能量是飞轮储能技术的发展趋势。以城市轻轨刹车动能再生为应用背景，研制了20 kW/1 kWh的飞轮储能系统。采用ANSYS对该飞轮转子支承系统进行动力学建模与仿真，计算出轴系主振型、临界转速与模态阻尼比；并对机座、真空套筒等非转动部件进行模态分析。进行了多次飞轮升降速试验，实时监测并记录飞轮运行全过程的幅频特性。试验结果与数值仿真的一致性较好，为飞轮系统的优化与改进提供可靠的理论与试验依据。

| Abstract: | The development trend of flywheel energy storage technology is high power and large capacity. The 20kW/1kWh of flywheel energy storage system was developed for the application background of regenerating break energy in urban rail-traffic. Based on ANSYS software, the dynamic model of the flywheel rotor-bearing-damper system was built to calculate critical speeds, mode shapes and modal damping ratios at different speeds, and modal analysis of the flywheel frame and vacuum container was also carried out. The amplitude-frequency responses of the flywheel dynamic system were obtained in a number of spin tests. The experimental results are in agreement with the ones of numerical simulation, which provides a reliable theoretical and experiment basis for optimization and improvement of the flywheel system. |
