Thermal Effects in Mechatronic Systems (FSI-RQM)

Academic year 2021/2022
Supervisor: doc. Ing. Radek Vlach, Ph.D.  
Supervising institute: ÚMTMB all courses guaranted by this institute
Teaching language: Czech
Aims of the course unit:
The aim of the course is to familiarise students with thermal phenomena in mechatronics. They will learn how to use numerical and experimental methods for description of thermal phenomena in mechatronic systems, especially electrical appliances and drives.
Learning outcomes and competences:
Students will be able to solve thermal phenomena in mechanic systems. They will acquire basic knowledge necessary for measuring of temperature and airflow in mechatronic systems.
Prerequisites:
Students are expected to have basic knowledge of programming.
Course contents:
The course deals with the basic terms of thermomechanics and heat transfer necessary for description thermal phenomena in machatronic systems. Also discussed is the effect of thermal phenomena on the function of mechatrinic systems.
Teaching methods and criteria:
The course is taught through lectures explaining the basic principles and theory of the discipline. Teaching is suplemented by practical laboratory work.
Assesment methods and criteria linked to learning outcomes:
Attendance at numerical, laboratory and computer exercises is obligatory. Students are required to submit the required number of reports, as well as the prescribed number of individual projects. ourse-unit credit is awarded on results in exercises (max. 30 points). The exam has an oral and a written part (max. 70 points).
Controlled participation in lessons:
Attendance at practical training is obligatory.
Type of course unit:
    Lecture  13 × 2 hrs. optionally                  
    Laboratory exercise  13 × 1 hrs. compulsory
