Contact pressure distribution of Multi-cone friction pair considering capsizing moment and stress singularity at the interface end

Abstract

Contact characteristics of friction pair play a crucial role in the torque transmission capacity and temperature rise prediction of automotive clutches. In this study, a Multi-cone friction pair used in wet clutches has been proposed. Each pair of conical contact is considered as the contact between a finite stiffness punch and an elastic half-plane, and 2D finite element (FE) models are developed to calculate the contact load assignments. Considering the capsizing moment and stress singularity at the end of the contact interface, an analytic model is established to obtain the contact pressure distribution on each conical contact interface based on the results of contact load assignments. Finally, the numerical examples are given, and the influences of axial load, mating material characteristics, friction coefficient, and cone angle on contact pressure distribution have been discussed in detail, which supplies the guidance of parameters design for Multi-cone friction pair.

“…Global climate warming is a phenomenon related to nature [4] . It is due to the continuous accumulation of the greenhouse effect, resulting in the imbalance of energy absorbed and emitted by the ground-air system, and the continuous accumulation of energy in the ground-air system, resulting in temperature rise and global climate warmin [5] . Therefore, with the intensification of global warming, the distribution of global temperature in the future has become an important focus issue [9] .…”
