Machine Learning Based Surrogate Models for the Thermal Behavior of Multi-Plate Clutches
Applied System Innovation, 2022 Multi-plate clutches play safety-critical roles in many applications. For this reason, correct functioning and safe operation are essential. Spontaneous damages are particularly critical because the failure of the clutch can lead to a failure of the ...

Friction Behavior of Pre-Damaged Wet-Running Multi-Plate Clutches in an Endurance Test
Lubricants, 2020 Wet-running multi-plate clutches should be prevented from failing due to the often safety-relevant functions they fulfill in the drive train. In addition to long-term damage, spontaneous damage is of particular relevance for failures.
