   Tribology

Tribological problems arise in almost all mechanical systems. Therefore the target groups are the firms that are in mechanical engineering, in particular users of ceramic materials with their focus on:
Friction applications (for example clutches, brakes)
  • Slide applications (for example ceramic slide bearings and seals in pump construction)
  • Rolling applications (for example ceramic roller bearings for applications under extreme conditions)
  • Metal forming (for example ceramic rolling- and deep-drawing tools)
  • Friction applications (for example clutches, brakes)

A full understanding of component behaviur is often only reached by modelling and simulation of the tribological system.

Expertise

Modelling and simulation of tribological systems
  • Calculation of local loads during power transmission in mechanical systems
  • Simulation of the lubricated slide contact under consideration of roughness and micro hydrodynamics
  • Determination of flash temperatures in solid contacts as a result of friction processes
  • Calculation of loads in the rolling contact by means of analytical solutions and finite elements method
  • Damage modelling in the rolling contact of ceramic materials
  • Numerical modelling and design of layers and layer systems
Accompanying development of test chain and components optimization beginning with the materials selection up to component tests in laboratory under production relevant conditions
