Fault Mechanism and System Structure of In-Transit Vehicles Safety Condition Monitoring in Rail Transit

With the fast development of rail transit in recent years in China, it has now become one of the most significant parts of the country’s transportation system. It is therefore in this background that we find the safety of in-transit vehicles in rail transit in dire need of attention. Thus this paper focuses on the safety condition monitoring of in-transit vehicles in rail transit, and namely two aspects of it, the fault mechanism of certain components and the structure of the monitoring system. First, a review and a summary of past works on the safety condition monitoring of in-transit vehicles are done on a scope of studies both domestic and international. From there, we focus our analysis on the fault mechanism of a key component, the bearing of the running gear in the rail transit vehicle, providing insight into the monitoring of it and the prevention of its fault. Finally, a structure of an in-transit vehicle safety condition monitoring system is proposed, offering theoretical support for designing such monitoring systems.
