轨道车辆异常振动预警系统的技术方案研究

On-board Mechanical Fault Detection System for Rail Vehicles

介绍了目前车载故障监测及预警方面的发展情况和技术水平,分析了铁路车辆与轨道间振动的特殊性,提出了一种适合于轨道车辆走行部机械故障预警系统的技术方案,即拟从能量角度出发的机械故障的识别方法。通过仿真分析模拟,验证了此方法的可行性。

Based on a literature survey on the fault detection technology for rail vehicles and the analysis of special characteristic of running gear of rail vehicles, a concept on- board mechanical fault detection system for the rail vehicles is put forward in the paper. It employs conversation of the energy - based method to identify the mechanical faults.And a simulation has been carried out for evaluation of the method.
