Tribology and Drive Technology

© TU Graz/IME

This area deals with the simulation- and test-supported development of machine elements, up to complete systems which are mainly located in the automotive sector.

The drive technology has long been a central cornerstone of the institute. The method-supported development of drive-related machine elements and subsystems up to entire drive trains (transmission, electric drive axle) is carried out. The combination of simulation and testing takes place in the AVL - TU Graz Transmission Center with its test rigs as a test and research environment.

In particular, the knowledge of the tribological processes in drive systems is in terms of efficiency and durability inevitable. Friction and wear processes are highly complex and still represent an interesting field of research.
