中文摘要：
研究了一种适用于非动力车辆的非摩擦制动技术——旋转型永磁涡流技术。根据涡流制动原理,以CRH2拖车转向架为对象,设计了旋转型永磁涡流制动装置。运用ANSYS软件着重进行了旋转型永磁涡流制动装置磁场的瞬态分析,得到在不同速度下感应盘所能提供的制动功率。最后从制动装置的永磁体磁极对数、磁极周向距离、极片厚度、空隙宽度等方面对漏磁造成的运行阻力进行了分析,并提出相应的措施。
英文摘要：
This paper studied the non-friction rotating permanent magnet eddy current brake technique,which was used on non-powered vehicles.Based on the theory of eddy current brake,the rotating permanent magnet eddy current brake was designed according to the structure of CRH2 EMU＇s trailer bogie.The dynamic analyses of rotating permanent magnet eddy current brake was made by ANSYS,the brake＇s power at different speeds was calculated.At different numbers of pole pairs,circumferential distances of the pole,thickness of pole pad and gap widths of rotating permanent magnet eddy current brake,the running resistances caused by leakage of magnet field were analyzed.The conclusions got from this article provide some theory foundations for application of the rotation eddy current brake.
