Background Low adhesion Reduced traction, Reduced traction, Extended braking distance, etc. etc. This project focusses on real time estimation of low adhesion at the wheel rail interface Early stage of the project was to develop simulation model of a simplified rail vehicle to study the dynamics of railway vehicle systems UKACC PhD Presentation Showcase Slide 2

Future Work UKACC PhD Presentation Showcase 1.Increasing complexity in the vehicle suspension system 2.Non-linear wheel rail contact profile Condition Monitoring Slide 5
6
Conclusion Simulations of rail vehicle modelling are being developed to perform real time estimation of low adhesion Various filtering techniques will be analysed for the estimation of contact parameters These techniques will be incorporated on more complex models with non linear characteristics in the suspension system and contact parameters of the rail vehicle UKACC PhD Presentation Showcase Slide 6
