摘要
轨道几何不平顺一直是轨道检测的主要项目,它是影响列车运行安全和平稳性最主要的参数。通过不平顺轨道的数值模拟以及车辆轨道动力学仿真,对惯性法测量轨道不平顺进行了仿真研究,分析了各不平顺参数的检测方法,研究了陀螺仪性能对测量精度的影响。
Because of the main parameters for safe and smooth train running, track geometry irregularity measurement is an important part of the track inspection. The simulation of track irregularity measurement based on inertial method is discussed, by use of the numerical simulation of track irregularities and the train-track dynamics. The irregularities are analyzed and the influences of the gyro performance on accuracy measurement are researched.
