Research Focus

The research focus is on methods and processes for the development of dry and lubricated friction systems in complex drive system solutions:

  • Modelling of tribotechnical systems
  • Explanatory models for tribological contacts
  • Computer-based simulation of tribological contacts in the overall system
  • Observance of interaction in the overall system
  • Alternative friction materials

 

Service Offer

We are your partner for problems requiring experimental and virtual research and validation of dry-running and lubricated friction systems.

  • Theoretical and experimental investigation in all test categories
  • Customer-specific optimised methods and processes for development, design and validation of friction systems
  • Joint development and validation of innovative products
  • Optimisation of components and systems

 

Equipment

We offer the following simulation and test equipment which is especially useful for probing and examining friction systems:

  • Dry friction model test bench (TRM)
    • Investigation of tribological behaviour of test pieces

    • A fixed friction disk allows the application of many different kinds of measuring equipment

    • Further information about the test bench can be found in the flyer which will soon be available for downloading here.

  • Dry friction test bench (TRP)
    • Investigation of test pieces, clutch plates and clutch systems under load-like boundary conditions

    • Replication of powertrain stiffness and simulation of mass moments of inertia

    • Further information about the test bench can be found in the flyer which will soon be available for downloading here

  • Powertrain in the loop test bench (PLP)
    • Investigation into how friction systems interact with the overall powertrain

    • Further information about the test bench can be found in the flyer which will soon be available for downloading here.

  • Continuous slip test bench (DSP)
    • Investigation of wet-running multi-disk clutches and brakes with simultaneous rotation of inner and outer disks

    • Investigation of switch operation as well as continuous slip operation

    • Further information about the test bench can be found in the flyer which will soon be available for downloading here.

  • Multi-slip test bench (MSP)
    • Differentiated investigation of friction pairs through the combination of three possible sliding portions: tangential slip, radial slip and spin

    • Cyclic meshing of friction contacts

    • Further information about the test bench can be found in the flyer which will soon be available for downloading here.
