Experimental Methods (FSI-QEM)

Academic year 2021/2022
Supervisor: prof. Ing. Josef Štětina, Ph.D.  
Supervising institute: ÚADI all courses guaranted by this institute
Teaching language: Czech
Aims of the course unit:
The aim of the course is to acquaint students with measurement methods and approaches to experimental problem solving with a focus on internal combustion engines and motor vehicles. It is essential to obtain a basic idea of the complexity of experimental work and current technical possibilities for their solution.
Learning outcomes and competences:
The graduate of the course will acquire theoretical knowledge and practical experience with experimental work with an emphasis on the use of computers in measuring and processing the experiment is able to simplify problems to choose the solution procedure and to orientate in the selection of appropriate measuring techniques.
Prerequisites:
Basic knowledge of mathematics, physics, mechanics and electrical engineering at the bachelor's degree in mechanical engineering.
Course contents:
Learning outcomes of the course unit The subject "Experimental Methods" acquaints students with procedures and methods used in the experimental solution of tasks in the program of automotive and traffic engineering in order to be able to apply them in practice. It explains the basics of modern methods of measuring mechanical quantities and defines the structure of the measuring and control instrument chain. Measurement of kinematic quantities, forces, moments, pressure, temperature and noise.
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:
Assessment methods and criteria linked to learning outcomes: Conditions for awarding the course-unit credit: active participation in seminars, elaboration of seminars, and passing a credit test. Exam: the exam examines the acquisition of knowledge gained in lectures, is focused primarily on the application of this knowledge to measurement and instrumentation, the exam is a written test and the possibility of oral verification of knowledge, up to 30% of the evaluation is the classification of laboratory exercises.
Controlled participation in lessons:
Attendance at the exercise is mandatory. Absence is solved with the teacher entering a substitute assignment.
