Methods and Tools

Various methods and tools are used in research and development in the field of special drives and energy converters:

  • On the one hand, we rely on theoretical principles from the fields of thermodynamics, fluid mechanics, piston engines and internal combustion engines as well as drive technology.
  • On the other hand, simulation tools such as 3D CFD, finite elements and multi-body dynamic codes are used. In addition to commercial simulation tools, the department also develops its own longitudinal dynamics and thermodynamic simulation tools and uses in-house tools (engine process simulations, ...). 
  • For conception and design, we use 3D CAD systems like Catia © and ProEngineer © in different versions according to requirements and customer wishes.

Test Benches

The experimental equipment of the research area includes:

  • 5 engine test benches for motored and fired operation in the power range from 20kW to 200kW
  • Highly dynamic chassis dynamometer for two-wheeler vehicles (homologation capable)
  • Exhaust gas measuring systems for the test benches as well as mobile exhaust gas measuring systems for use in the RDE operation of two-wheeler vehicles 
  • Mobile measuring technology for fast data acquisition (e.g. indexing) on the vehicle, especially on two-wheeler vehicles.
  • Control unit systems such as MicroAutobox and others



We use 1D & 3D CFD software, finite element methods, multi-body systems and other codes from various manufacturers for simulated investigations. In addition to using all common software tools, we also develop special codes for specific simulation problems. This concerns among other things:

  • Thermodynamic analysis and simulation of work processes,
  • 1D/3D flow simulation 
  • Longitudinal dynamics simulation for the calculation of energy demand, drivability and emissions of two-wheelers, in particular hybrid drives and ECU simulations.
  • FE structural analysis, thermal analysis
  • Acoustics Modal analysis, Acoustic intensity
  • CAx in vehicle and engine development (Virtual Engineering)



For the design and layout process, we use interrelated methods from 3D CAD and simulation as well as PDM. The software systems for the design are among others:

  • CATIA V5 incl. surface generation, ....
