Abstract
Complex modern transport systems need to be reliable and operated at high
efficiency with the cost of breakdowns kept at a minimum. The well known
strategy for maintaining the operation of any integrated system is to choose the
appropriate parameters to be monitored continuously. Then, any fault or
deviation from the normal operation condition would be detected and the
necessary action could be taken to avoid any disruption to the operation and
avoid any accident with devastating consequences.
This paper looks at monitoring of parameters for essential components in rail
transport such as axle vibration and pantograph load, and gives the detail of the
systems used in monitoring their operation. The continuously measured data
such as torque on the main gearbox shaft or load/acceleration on the pantograph
enables diagnosis of potential issues within such systems on routinely operating
trains. Variations from the expected values can be detected early and corrected
to avoid compromising passenger safety from a more severe failure in the future.
The paper discusses the system designed for monitoring the transmitted
torque and bending moments in the rail vehicle axle as a mean for identification
of any abnormal loading.
Pantograph failures due to complex interactions between the overhead line
(OHL) and pantograph structure cause significant problems to railway industry
worldwide.
This paper also describes the design, development and test results from the
first fully proven Pantograph Monitoring System which is now deployed on
routinely operating trains in the UK.
