Course detail

Experimental Methods in Tribology

FSI-9EXT Acad. year: 2024/2025 Both semester

The aim of this course is to provide students with a general and useful introduction to the experimental methods for measurement and analysis of friction, lubrication and wear. The course covers fundamentals of design of experiment, determination of precision, accuracy and errors of measurement and statistical analysis of data.

Entry knowledge

Knowledge from general courses on mechanics, physics, math, machine elements, materials technology and surface engineering.

Rules for evaluation and completion of the course

Conditions for gaining the exam:

  • submission and defense of individual work on measurement or experimental analysis of selected tribological problem. The work would include theoretical description, error and measurement quality analysis and design of results evaluation.

Absence from lessons may be compensated for according to instructions of the teacher.

Aims

The main aim is to provide basic knowledge of the experimental methods, theory of measurement and experiments in the field of tribology with respect to the topic of PhD thesis.

  • The ability to identify the key problems for experimental validation of tribological problems.
  • The ability to select proper experimental methods with respect to the specific problems in the field of tribology.
  • The ability to design experiments and assess quality of measurements.
  • The ability to statistically evaluate results.
