Influence of Material Parameters on the Contact Pressure Characteristics of a Multi-Disc Clutch

As an essential part of the transmission, the life of the clutch directly affects the stability of the transmission. In this paper, a finite element model and a thermodynamic numerical model of a multi-disc clutch are established to investigate the influence of material parameters on the contact pre...
