相比于其他储能方式, 飞轮储能的高功率密度和高效率能量存储方法有很大的优越性, 但也带来了其质量较大的困扰.基于传统模式单级飞轮储能结构, 提出了一种新型两级式飞轮储能装置, 并通过选用某种确定车型的车辆制动时所能够回收的能量, 证明在一定程度上提供相同的储能容量时, 该装置的质量可以明显降低.基于证明结果, 通过Ansys软件对飞轮转子系统进行了10阶的模态分析和等效应力分析.仿真结果表明:该飞轮转子系统不会发生共振情况且满足强度要求, 可以安全可靠的工作.%This paper proposes a two-stage flywheel energy storage device based on the conventional one-stage flywheel configuration. It was found that, for a given energy storage capacity, the twostage device could have a lighter mass and a smaller volume. Based on the above, a 10 th order modal analysis and an equivalent stress analysis were carried out on the flywheel rotor system in an Ansys software environment. The simulation results showed no resonance to the modified flywheel rotor system, meeting the strength requirements.
