Abstract
In multi-disc clutches, the separator discs slide relatively to the friction discs during engagement, and usually display ?hot spots? in a sinusoidal shape on both surfaces of a separator disc. Explanations based on ?perturbation method? were widely used to describe the generation and development of hot spots in seals, brakes and clutches. In this study, a multi-disc clutch experiment was implemented to observe hot spots phenomenon, based on the results, a scenario of hot spots generation mechanism on thin disc is introduced and a 3D finite element non- uniform contact model of multi-disc clutch was developed to simulate the developing process of hot spots and illustrate the generation mechanism scenario.
