SIMULATION MODELLING OF THE RAILWAY VEHICLE GUIDANCE MECHANISM Priya Parthasarathy Supervisors- Dr.Christopher Ward Dr.Roger Dixon UKACC PhD Presentation Showcase
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
Introduction and Initial Project Aim UKACC PhD Presentation Showcase Fig 1 Simplified rail vehicle model with single wheelset and suspended mass Slide 3
UKACC PhD Presentation Showcase Fig 2 Lateral position of the wheelset for the track displacement (Simulation model) Fig 3 Lateral position of the wheelset for the track displacement (Simplified model) Slide 4 Results Fig 4 Yaw angle of the wheelset for the Simulation model Fig 5 Yaw angle of the wheelset for the Simplified model
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
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
