Modelling of Machinery Systems

FSI-ZMS-AAcad. year: 2010/2011

This subject yields theoretical and practical knowledge concerning mathematical modeling and computer simulation of mechanical systems for reasons of behavior prediction and optimization possibilities. Following themes are concerned: methods of mathematical modeling of mechanical systems, software means of computer simulation, basis of MATLAB/Simulink, examples of MATLAB/Simulink use in individual areas, characteristic of toolboxes chosen for designers, creation of mathematical and simulation models in chosen mechanical applications.

Aims

Aim of this course is to make students acquainted with basic principles of mathematical modeling and computer simulation of mechanical systems – an interdisciplinary field, dealing with formulation of mathematic-physical relations, describing inner and outer behavior of such systems at their function; aside from this formulation, the further aim is to learn students to implement models practically by means of computer and to draw necessary conclusions from such simulation.

Specification of controlled education, way of implementation and compensation for absences

Attendance is overseen by tutor, an active taking part in the seminar is a condition for receiving a credit.
