摘要

涡流制动器的工作原理是基于刚性导电铁芯在磁场中的相对运动。涡流制动器结构简单，但在工作中涉及到复杂的数学关系。过去，许多研究者对涡流制动器的问题进行了研究。但大多数方法只考虑了感应电流的分布和产生的磁场强度，而忽略了集肤效应，而集肤效应在涡流制动器的转矩-速度特性中起着重要作用。本文从理论上和经验上研究了以集肤效应为重点的圆柱形涡流制动器的工作原理。

Influence of skin effect on torque of cylindrical eddy current brake

The principle operation of eddy current brakes is based on relative motion of a rigid conductive core in a magnetic field. In spite of simple structure, eddy current brakes employ complicated mathematical relations in operation. In the past, many researchers have investigated the problems of eddy current brakes. But most of them only considered distribution of induced currents and the resultant magnetic field intensity and ignore the skin effect whereas skin effect plays a significant role in torque - speed characteristic of eddy current brakes. In this paper we have studied the operation of cylindrical eddy current brake emphasizing skin effect theoretically and empirically.
