摘要
以10 kW·h磁悬浮储能飞轮转子为研究对象,详细地阐明了转子结构组成及各部件的连接方式和功能,提出了 7项转子设计准则,并给出了转子的设计参数.采用ANSYS有限元软件分析了最高转速和极限转速下的轮体应力,结果均超出材料的许用强度.通过对转子各个配合零部件在静态与极限转速下的过盈量分析,所有零部件均未超过自身材料强度,且过盈接触面均未发生分离.通过对转子临界转速与不平衡响应分析得出,转子的工作转速内不存在临界转速,且稳定性良好.文中通过对储能飞轮转子设计的研究,从多个方面分析了飞轮转子的性能,为其他规格的储能飞轮转子的结构设计提供了设计方法及参考依据.
Abstract
In this article,with the focus on the 10 kW·h magnetically-levitated energy-storage flywheel rotor,efforts to explore its structure as well as each part's connection mode and function;7 standards of rotor design are put forward and the parameters are given.The finite-element software ANSYS is used to analyze the stress exerted on the wheel body at the maximum speed and the limit speed,and the results show that the requirements of material strength cannot be met.Through the interference analysis on the rotor's each part in the static state and at the limit speed,it is found that all the requirements of material strength are met and the interference contact surface is not separated.Through the analysis on the rotor's critical speed and unbalance response,it is concluded that there is no critical speed within the rotor's the working speed,and desirable stability is ensured.Therefore,the energy-storage flywheel rotor's performance is analyzed from many aspects;this study provides methods and reference for structural design of those flywheel rotors with other specifications.
