Applications of ultrasonics to rail/wheel performance monitoring. Wed. JAN 27, 2021; 09:00 EST / 14:00 GMT
This presentation gives an overview of the recent developments using non-invasive ultrasonics for a number of different novel wheel-rail measurement applications. Earlier work in the area has been confined to lab based experiments to demonstrate the measurement methods. Recently work has been undertaken to progress the technology to the field.
The first application presented uses a non-permanent under-rail sensor assembly where it is possible to infer measurements of wheel contact position on the rail, L/V, and potentially axle yaw (using a sensor pair).
A second body of work is underway to demonstrate the measurement of longitudinal rail stress using a new web-mounted multi-planar ultrasonic sensor assembly. The results from lab tests and initial field trials show much promise in this new technology.
