Course detail

Experimental Methods

FSI-QEMAcad. year: 2022/2023

The course "Experimental Methods" introduces students to the procedures and methods used in experimental problem solving in the Automotive and Traffic Engineering program so that they are able to apply them in practice. It explains the basics of modern methods for measuring mechanical quantities and defines the structure of the measurement and control instrumentation chain. Measures kinematic quantities, forces, moments, pressure, temperature and noise.

Learning outcomes of the course unit

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 level of a bachelor's degree in engineering.

Co-requisites

Not applicable.

Planned learning activities and teaching methods

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 50% of the evaluation is the classification of laboratory exercises.

Aims

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.

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

Attendance at the exercise is mandatory. Absence is solved with the teacher entering a substitute assignment.
