THE EFFECT OF CONSTRAINT CONDITIONS ON THE CONTACT PRESSURE DISTRIBUTION OF MULTI-DISC FRICTION CLUTCHES
Journal Title: Tribologia - Year 2015, Vol 264, Issue 6
Abstract
High thermal stresses generated between the contact surfaces in a clutch system, e.g., multi-disc friction clutch (back plate, clutch discs, separators, and piston), due to the friction heat generated during the slipping period are considered to be one of the main reasons for friction clutch failure. The finite element method has been used to study the contact pressure distribution of a multi-disc clutch (working in dry conditions) when all parts are closing together and the clutch system starts to engage. The augmented Lagrange algorithm is used to obtain the contact pressure distribution of the friction surfaces under different restriction conditions. Analysis has been completed using the developed axisymmetric model that is used to simulate the multi-disc clutch system.
