Learning outcomes
|
The aim of the subject is to acquaint the students with the theory of road vehicles motion. To deepen their theoretical knowledge of the principles of wheel rolling, driving dynamics, directional and dynamic stability of vehicles. To teach analyzing the application of forces and moments and ability to evaluate responses of vehicle to the forces applied. On the basis of this knowledge, to teach the students to determine a correct procedure for calculating the basic parameters. To form a theoretical base for assessing the road vehicles.
After completion of the subject, the student is able to analyze acting forces and moments. He/she can deduce dependencies for determining the intensity of rolling resistance and other forces and moments. He/she is able to deduce the dependencies for determining the vehicle stability conditions. He/she is able to give theoretical reasons of vehicle's driving behaviour and determine the influence of particular parameters of the vehicle. They are able to apply theoretical dependencies in practical examples when calculating the basic parameters of vehicles.

Assessment methods and criteria
|
Oral examination
The condition for participation in the exam is for students of the full-time form of study to obtain credit. The credit confirms that the student has sufficiently participated in the lessons and that he/she met the requirements (credit test). The specific requirements will be defined by a lecturer in the first week of the semester. The subject exam (oral and written) for full-time form of study is determined in accordance with the UPa Study and Examination Regulations.
