Course Title RAIL VEHICLE DYNAMICS AND TRAIN-TRACK INTERACTION
Course Type Mono-Disciplinary Course
Credits (CFU / ECTS) 6.0
Semester Second Semester
Course Description Rail vehicle modelling: detailed rail vehicle structure, wheel-rail contact forces (creepage, geometrical aspects of wheel-rail contact, models for contact forces). Modelling of suspension components. Semi analytical approaches: wheelset on tangent track and curve, bogie on tangent track and curve: dynamics and steady state condition. Numerical model: full rail vehicle model dynamics. Track and infrastructure modelling: track typologies for standard lines, high speed lines and urban and metro lines. Modelling of the main track elements: rail, fastenings, sleeper, slab, elastomeric elements. Train-track-structure interaction: time domain and frequency domain models for train-track and train-bridge/tunnel interaction. Damage mechanism on wheel and rail: wear and RCF on wheel and rail, fatigue and crack propagation in wheelset axle, fatigue in rail welded joints. Main aspects, phenomenological description, testing and modelling. Effects of environmental condition: temperature, corrosion. Outcomes on maintenance: damage detection techniques, planning of checking intervals. Environmental impact of railway transportation: ground borne vibration, generated air borne noise. Phenomenological description, relationship with wheel-rail contact forces and wheel-rail dynamics. Basic modelling, measurement techniques and raw data analysis and processing.
