Course detail

Calculation Models

FSI-QMOAcad. year: 2013/2014

The subject should serve as an introduction of the most important current calculation models used in the development of state-of-the-art powertrains and vehicles to the students. The emphasis is laid upon the mathematical and physical foundations of calculation models and the respective software as well as the verification of results of the computer modelling by way of appropriate experimental methods. There are presented examples of powertrain dynamics solutions, for example 3D computational models of powertrain components, unsteady loaded slide and roller bearings, piston assembly dynamics, applied fatigue of powertrain components or turbocharger rotor dynamics.

Assesment methods and criteria linked to learning outcomes

The course-unit credit requirements:
The orientation at physical fundamentals of presented problems and the knowledge of practical solving methods , leading to individual work especially on a diploma thesis and in engineering practice after completing studies. The ability to solve problems using computer technology and necessary advanced software equipment. Students have to individually elaborate assigned tasks without significant mistakes. Together with evaluating them the continuous study checking is carried out.
Examination:
The course is concluded by a final test, as well as oral discussion.
Final evaluation consists of:
1. Evaluation of the individual work on seminars (individually elaborated tasks).
2. The results of written and oral parts of the exam.
