摘要
为实现在既有运营线路上动态测量轨道不平顺,对通过轴箱的加速度信息计算轨道不平顺的方法进行研究。分析了在时域和频域上使用轴箱加速度轨道不平顺的计算方法,并在同济大学轨道交通实验线上进行实验测试。分别使用频域和时域计算法对测试数据进行分析处理,得到轨道不平顺。对使用上述两种方法的计算结果进行验证比较和理论分析。实验结果表明,通过轴箱上的加速度进行计算能够反映轨道上的不平顺情况,并且在时域上计算的效果更好。
In order to measure the track irregularity on the existing operating line dynamically,methods of calculating track irregularity based on the axle box acceleration data is researched.Track irregularity can be calculated in time and frequency domain separately based on the acceleration signal from axle box.An experiment is made at Tongji rail transit test circuit to compare the performance of two methods.The experiment shows that both measurement methods based on axle box acceleration can reflect the track irregularity and the result calculated in the time domain performs better.
