Course detail

Experimental Methods

FSI-QEM Acad. year: 2023/2024 Summer semester

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.

Entry knowledge

Basic knowledge of mathematics, physics, mechanics and electrical engineering at the level of a bachelor's degree in engineering.

Rules for evaluation and completion of the course

Conditions for credit: active participation in the exercise, and preparation of measurement protocols. Examination: the examination verifies the acquisition of knowledge acquired in lectures, it is mainly oriented on the application of this knowledge to measurement and instrumentation, the examination is written in the form of a test and the possibility of oral verification of knowledge, up to 50% of the evaluation consists of the classification of measurement protocols.


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

Aims

The aim of the course is to acquaint students with measurement methods and approaches to experimental problem solving with a focus on vehicles and their drivetrains (BEV, ICE, HEV). It is essential to obtain a basic idea of the complexity of experimental work and current technical possibilities for their solution.


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.
