Vergleich von Reibungszahlverläufen von nasslaufenden Friktionskontakten im gezielten Schlupfbetrieb unter dynamischer Anregung

摘要

This paper presents test results regarding the effects of different dynamic excitations at the clutch input on friction coefficient curves. The effects were investigated under the circumstance with and without interaction between wet clutch system and remaining powertrain components. Based on the comparison of these results, it is evaluated whether a consideration of system interactions is necessary to determine the friction coefficient and which differences occur in the friction coefficient curves. In addition, an investigation environment based on a model is introduced with which the system interactions can be represented by a sufficiently accurate mapping of the dynamic characteristics of a powertrain.
