Learning outcomes
|
The aim of the subject is to acquaint the students with the basics of motion mechanics of the road vehicles. To teach them about the dependency between application of forces and moments in the vehicle and its behaviour. On the basis of this knowledge to teach the students the procedure to calculate forces and moments affecting the vehicle. To acquaint them with the theoretical basics of accessing the riding qualities of the road vehicles.
After passing the subject, the student is able to determinate forces and moments affecting the vehicle. He/she is able to calculate the intensity of rolling resistance and other forces and moments. He/she is able to determine the conditions for stability of the vehicle and the stability-affecting parameters. He/she is acquainted with theoretical requirements for the main constructional groups, in view of their proper function. He/she is able to define the conditions and requirements in terms of the road vehicle properties required.

Assessment methods and criteria
|
Oral examination, Written examination
In the course of the semester and at the final exam, the student has to demonstrate his/her understanding of the problems solved and the ability to independently define the conditions for setting the necessary parameters of a vehicle. To define and calculate the forces and moments affecting the vehicle in motion. Concrete requirements shall be given to the students by the tutor in the first week of the semester.
