Course content

Lectures and exercises are formed into 13 blocks, practical examples and their implementation will be solved during the exercises: 1) Design elements of road vehicles and their mechanical (dynamical) characteristics 2) Parameter identification and computational models of main design elements 3) Computational modelling of tires - summary of approaches, model implementation, parameter identification 4) Longitudinal dynamics of road vehicles - acceleration, braking 5) Vertical dynamics of road vehicles - ride comfort, vibration, force effects during a ride on uneven surface, fatigue 6) Horizontal dynamics of road vehicles - handling, steering, stability 7) Drives and powertrains of road vehicles - whole powertrain, its dynamical properties, gearboxes, differential, combustion engines, electromotors 8) Formula Student (SAE), combustion engine version, electroformula, design and powertrain optimization 9) Specific problems of the single-track road vehicles dynamics 10) Rail vehicles - nonlinear computational model of wheel-rail contact, main design elements and their models 11) Rail vehicles - computational models for stability evaluation and dynamic properties of rail vehicles 12) Rail vehicles - powertrain, pantograph-catenary interaction, fatigue 13) Normative calculations in the field of mechanics/dynamics of road and rail vehicles, homologation, industrial problem and examples
