Abstract
In this study FE contact and thermal sliding analysis of an alumina-steel dry
sliding friction pair was performed to investigate the real contact area, the
contact pressure distribution and the temperature distribution considering the real
worn topographies. A friction test was carried out to simulate the dry sliding
friction of sliding pairs on the test rig designed for this purpose. The applied
algorithm describes the real processes of the contact area formation, although
local micro-level calculations will be necessary in the future.
Keywords: dry sliding friction, real contact area, contact temperature.
1 Introduction
Ceramics structural components provide novel opportunities for engineers due to
their exceptional static and tribological characteristics. High purity alumina
ceramics have some advantages such as good heat conduction, thermal stability,
wear resistance, and high compression strength; they provide a promising
friction material for clutches, CVTs, and brakes. Nevertheless, the properties of
ceramic materials are unknown or only partially known in a number of areas. In
the course of development, the special mechanical properties of ceramics require
a new approach in terms of design and sizing. This requirement particularly
applies to complex loads, such as sliding friction. Heat generation plays a
dominant part in the behaviour of tribological systems of dry sliding friction. The
investigation of heat generation requires contact phenomena to be studied.
Characterization of the real tribological process requires the joint investigation of
