Diagnostic Method of Instability in Serpentine Motion of High-speed Locomotives
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.
