Learning outcomes
|
The aim of this course is to acquaint the students with issues concerning guiding of a vehicle by a straight and a curved track, force actions between vehicle and track in curves. In a next part, the course deals with vehicle suspension, theory of vehicle body elastic seating, and basics of vehicle running dynamics.
After passing the course, student is capable of analysing vehicle running on straight and curved track with appropriate calculations - running behaviour, guiding of vehicles and safety against derailment. Furthermore, student can design basic parameters of vehicle suspension and analyse dynamic peformance of a vehicle running on straight and curved track.
