Learning outcomes
|
The aim of the course is to provide students with knowledge on theoretical principles and tools for analysis of rail vehicles, their running behaviour and interaction with the track.
After passing the course, the students have knowledge of principles of rail vehicle theory and they can use the knowledge in analysis of rail vehicle running and curve negotiation.
