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 be able to efficiently use possible functional extensions of the clutch system, such as vibration reduction, in future applications, sometimes hybrid powertrains, a targeted design of the tribological system is required. Knowledge of the relationships between frictional behavior and vibration-reducing effect is of central importance here. Also with regard to efficiency and environmental aspects, this represents a central topic in the validation of the modern coupling system.

Task:

Within the scope of the final thesis, correlations between the dynamic friction behavior and the vibration reduction function in the clutch system are to be investigated. For this purpose, measurement data are available from which, using existing methods, given evaluation variables are determined both for the friction behavior, such as average friction values, and for the vibration reduction effect in the frictional contact, and are then to be analyzed, sometimes by means of correlation analysis. The aim is to determine which variables in the frictional contact influence the reduction effect, how and why, in order to be able to optimize the frictional contact in a targeted manner in the future. The work will be concluded with a first scientific interpretation of the results.

Profile:
