Transmission machinery is widely used in railway vehicles and is an important co.ponent in driving the operation of trains.Such transmission co.ponents are prone to faults under long exposure to harsh environments and co.plex working co.ditions.This affects normal operation and order,and thus it is important to ensure their safe and reliable operation.Electrical signal-based diagnosis technology has advantages of easy signal acquisition,with no need to install additional sensors,nor embedded monitoring of the object co.ponents.It has gradually beco.e a research hotspot in the field of rail transportation diagnosis.This paper describes the fault modes of transmission machinery,takes the electrical signal-based diagnosis method as the entry point,co.lates and co.pares the existing diagnosis methods and research results in this field.It analyses their advantages and disadvantages,and finally puts forward problems for current and future research and development.
