Abstract

The critical speed of eddy current braking is a vital parameter in the design of eddy current braking devices. Currently, most simulations and experiments are used to determine the critical speed, which means a lot of time costs. This paper presents two laws of critical speed variation to help designers more quickly determine the critical speed of a particular eddy current braking device. At first, the structure and the critical speed principle of permanent magnet rotary eddy current brake (PMRECB) are described. Secondly, the finite element analysis is used to verify the accuracy of the two laws. Finally, the validity of the finite element model is confirmed by the eddy current braking test.

关键设计参数对涡流制动器临界速度的影响

涡流制动的临界速度是设计涡流制动装置的一个重要参数。目前，大多数情况下都是通过模拟和实验来确定临界速度，这意味着需要花费大量的时间成本。本文提出了两个临界转速变化规律，帮助设计人员更快地确定特定涡流制动装置的临界转速。首先，介绍了永磁旋转涡流制动器（PMRECB）的结构和临界转速原理。其次，利用有限元分析来验证这两个定律的准确性。最后，通过涡流制动试验证实了有限元模型的有效性。
