摘要
本文提出一种实时失稳监测算法,用于判定高速动车组蛇行失稳现象的发生。该算法采用时域和频域分析方法,用于诊断列车的失稳情况,并评估列车车体运行的平稳性。此外,该算法还建立了蛇行失稳判定阈值的确定方法,能够在运行过程中实时监测安全状况,减少安全隐患的发生。
A real-time instability monitoring algorithm for detecting the occurrence of snake-like instability phenomena in high-speed trainsets is proposed in this paper.The algorithm utilizes both time-domain and frequency-domain analysis methods to diagnose the instability of the train and evaluate the stability of the train's body movement.Furthermore,the algorithm establishes a method for determining the threshold of snake-like instability,enabling real-time monitoring of safety conditions during operation to prevent potential safety hazards.
