摘要： 为了解决钻机动力传动系统载荷波动大的问题，研制了1 MW/60 MJ飞轮储能系统实现动力调峰运行。分别采用传递矩阵法和有限元法对飞轮转子支承系统进行动力学建模，计算出飞轮轴系临界转速和振型；并使用有限元法对壳体等非转动部件建模并计算模态。进行飞轮升降速试验，实时监测降速过程中幅频特性和相频特性。对比数值仿真与试验结果一致，为飞轮储能系统的轴系设计与改进提供理论与试验依据。

Abstract:

A 1 MW/60 MJ flywheel energy storage system was developed for smoothing load fluctuations of a drilling rig power system. This paper introduces the use of transfer matrix method and the finite element method to model the flywheel rotor-support system, and to calculate the critical speeds and vibration modes of the flywheel shaft. The finite element method was also used to calculate the modal frequency of protective casing of the system. An experimental study was performed on flywheel acceleration and deceleration processes to obtain real-time the amplitude-frequency characteristics. The numerical simulations were in agreement with the experimental results. The results provide basis for the design and improvement of flywheel energy storage systems.

Key words: flywheel energy storage system, transfer matrix method, finite element method, modal analysis
