摘要
针对磁悬浮列车运行时车体与轨道不相接触的特点,给出了基于交叉感应回线的测速定位方法。在分析交叉感应回线电磁场特点的基础上,推导出回线磁感应强度、回线电感和天线感应电势的计算公式。另外,文中还给出了测速定位系统的具体结构。
A speed measuring and locating method for maglev vehicle, based on cross induction coils, isproposed in accordance with the characteristic that the vehicle does not touch the track while running. On thebasis of analysis on the electromagnetic field of the coils, calculation formulas for the magnetic flux densityand inductance of coils as well as induced potential of antennas are deduced. Besides, detail structure of thespeed measuring and locating system is given.
