| 摘 要： | 铁道车辆转向架的横向稳定性是指车辆以较高的速度在平直线路上运行,某一振型的振幅随着时间的延续而不断地扩大,这时就出现蛇行运动失稳。高速铁道车辆的研究急需关注的问题是防止出现蛇行失稳。通过在线实时监测其失稳是保障安全的手段之一,而如何实时监测蛇行失稳需要有满足时间约束条件的监测诊断算法,该算法即要满足有关标准的条件,又要具备实时监测的条件。研究了利用高斯混合模型(GMM)算法监测构架横向稳定性的机理与实现过程。该算法在25T列车安全监测系统得到应有,实践证明符合实时监测要求。

| Abstract: | On-line monitoring the bogie lateral stability of railway car is studied in this paper.Hunting behavior is the core of the safety running of high speed railway car.Half wave character analysis method is adopted and a new kind of bogie lateral stability index is obtained.There are two steps for real time monitoring the bogie stability.First the Gaussian Mixture Model(GMM) is used to train a probability model and then posterior probability can be used to monitor the bogie stability real time.The real time res... |
