SIMULATION MODELLING OF THE RAILWAY VEHICLE GUIDANCE MECHANISM Priya Parthasarathy Supervisors. Dr. Christopher Ward Dr. Roger Dixon UKACC Ph. D Presentation Showcase
Background Low adhesion Reduced traction, Extended braking distance, 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 Ph. D Presentation Showcase Slide 2
Introduction and Initial Project Aim Fig 1 Simplified rail vehicle model with single wheelset and suspended mass UKACC Ph. D Presentation Showcase Slide 3
Results Fig 2 Lateral position of the wheelset for the track displacement (Simulation model) Fig 4 Yaw angle of the wheelset for the Simulation model Fig 3 Lateral position of the wheelset for the track displacement (Simplified model) Fig 5 Yaw angle of the wheelset for the Simplified model UKACC Ph. D Presentation Showcase Slide 4
Future Work 1. Increasing complexity in the vehicle suspension system Condition Monitoring 2. Non-linear wheel rail contact profile UKACC Ph. D Presentation Showcase Slide 5
Conclusion Ø Simulations of rail vehicle modelling are being developed to perform real time estimation of low adhesion Ø Various filtering techniques will be analysed for the estimation of contact parameters Ø 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 Ph.
