列车轮对故障危及列车运行安全,对其准确检测是高速重载列车需要解决的关键问题。根据以往对列车走行部单个通路振动信号的处理方法,文章考虑了空间信息的利用,提出了基于多通道传感器的轮对故障检测方案。理论分析和仿真结果表明,该方案可以提高检测的灵敏度。
Train wheel failure endangers the safety of train operation and its accurate detection is the key problem to be solved in high-speed heavy-haul train. According to the previous method of processing the single lane vibration signal of the train running department, this paper considers the utilization of the spatial information and proposes the detection scheme of the wheelset fault based on multi-channel sensor. Theoretical analysis and simulation results show that this scheme can improve the sensitivity of detection.
