Wet clutch systems will continue to be present in many powertrain topologies in the future, not only in the field of vehicle technology, partly due to increasing hybridization and the automation of transmissions. The progressive change in mobility sometimes leads to changed forms of excitation in powertrains due to increasing hybridization. This also results in a change and increase in the demands on vibration-reducing components. The wet multi-plate clutch is one way of reducing vibrations as required in future hybrid powertrains. In order to meet the constant demand for improved efficiency, it is essential to consider the power losses in the system. Also with regard to environmental aspects, this represents a central topic in the validation of the slip-driven clutch system.

Task:

As part of the final thesis, a heat balance is to be carried out in various operating conditions of the wet clutch. The aim is to be able to estimate the "power loss" via a balance of supplied and dissipated energy. For this purpose, a method is to be developed with which the instantaneous power loss (in particular kinetic energy converted into thermal energy) can be approximated from measured variables. The existing test environment is to be expanded to include additional sensors, such as additional thermocouples, at suitable locations. Finally, the method will be applied to selected operating conditions in an experimental investigation and initial statements on occurring power losses in the slip-operated clutch system will be derived as a result.

Profile:

  • Bachelor's or Master's student in the field of mechanical engineering, mechatronics and information technology, engineering sciences or similar course of study.
  • Interest in test environments for experimental investigation
  • Independent and reliable way of working
  • Knowledge of MATLAB is an advantage
