Advanced Tribology (FSI-9EHD)

Academic year 2024/2025
Supervisor: prof. Ing. Martin Hartl, Ph.D.  
Supervising institute: ÚK all courses guaranted by this institute
Teaching language: Czech
Aims of the course unit:

Absolvents are able to analyse and solve advance problems of friction, lubrication and wear of contacts in machines. Focus is payed on improvement of abilities to understand, describe and interpret own observations of tribology experiments and simulations.

  • Ability to solve problems of tribological contact.
  • Ability to select, design and conduct appropriate tribological test.
  • Ability to apply fundamental possibilities of theoretical calculations.
  • Ability to compare results of experiments with theory, interpret results and make conclusions.
