论文摘要
在许多领域，例如智能电网，可再生能源，电动汽车和高功率应用，动力学/飞轮存储系统（FESS）已重新出现为重要技术。 FESS的设计和优化为每个质量（特定能量）和体积（能量密度）具有更高的能量。先前的研究，例如使用高强度材料和减少应力浓度，主要集中于设计和优化转子本身。但是，现代的FESS包括其他必不可少的组件，例如磁性轴承和需要轴的电动机/发电机。轴显着影响飞轮设计。本文研究了几种典型的飞轮设计及其压力分析。给出了设计转子轴组件的简化分析方法。发现与典型设计相比，无轴飞轮设计方法可以使能量密度的水平增加一倍。使用有限元分析和电动机/发电机的设计注意事项，使用有限元分析进一步优化了无轴飞轮。
Kinetic/Flywheel energy storage systems (FESS) have re-emerged as a vital technology in many areas such as smart grid, renewable energy, electric vehicle, and high-power applications. FESSs are designed and optimized to have higher energy per mass (specific energy) and volume (energy density). Prior research, such as the use of high-strength materials and the reduction of stress concentration, primarily focused on designing and optimizing the rotor itself. However, a modern FESS includes other indispensable components such as magnetic bearings and a motor/generator that requires a shaft. The shaft significantly impacts the flywheel design. This paper investigates several typical flywheel designs and their stress analysis. A simplified analysis method is given for designing rotor-shaft assembly. It is found that the shaftless flywheel design approach can double the energy density level when compared to typical designs. The shaftless flywheel is further optimized using finite element analysis with the magnetic bearing and motor/generators' design considerations.
