高速磁浮列车的安全速度防护问题研究

Study on Safety Speed Protection of the High Maglev Train

确定高速磁浮列车运行的安全速度范围,是列车运行控制系统要解决的首要问题．分析了德国高速磁浮列车的双限速度防护的特点,给出了安全速度防护曲线的求解思路及算法;并讨论了最不利的系统条件,指出要保证列车在最不利的条件下也处于系统的安全防护范围内．本文算例验证了算法的可行性．

The safety speed range of high speed Maglev is a key issue in train operation control system. First, based on the analysis of 2-limits speed protection of Germany high speed Maglev, the solving process and algorithm of safety speed protection curve are presented. Then it is pointed out that Maglev train must operate in the range of the safety speed protection curve even in the worst condition. Finally, the example verifies the algorithm.
