摘要:

针对高速磁浮轨道垂向不平顺检测，提出了一种基于惯性基准法原理的随车搭载型动态检测系统，并通过试验验证了该系统可满足±0.2 mm的检测误差要求.针对同步电机长定子齿槽形式的检测面，设计了一种削弱“齿槽纹波效应”的算法，可将齿槽形状引入的波动影响限制在±5 mm范围内.最后，根据检测要求分析有关传感器的选型，并提供了相应结构平台的初步设计考虑.

Abstract:

Based on the principle of inertia reference method, a kind of dynamic measurement system assembled on a vehicle was proposed to realize the measurement for the vertical irregularity of high speed maglev track. It is verified that the system can meet the requirements of measurement error within ±0.2 mm. As the detection surface was the cogging structure type of long stator of synchronous machine, an effective algorithm was put forward to reduce “cogging effect”. As a result, it can reduce the measurement fluctuate within ±5 mm which is caused by the cogging structure. Finally, according to the requirement of measurement, the selections of related sensors in the system were analyzed and the preliminary consideration of platform design was discussed.
