Experimental Determination of Contact Area
Journal Title: Tribology in Industry - Year 2015, Vol 37, Issue 4
Abstract
The main goal of this article is to experimentally evaluate the contact area and to compare the measured results with the different contact model theories. The experiment takes advantage of the electrical contact resistivity principle in a dry piston/cylinder liner test rig assembly. Analytical contact models are implemented into the computational simulation. The calculated contact area depends on the dynamics and precomputed database of contact pressure and contact area in the relation to the separation distance of surfaces. Multibody System (MBS) is augmented by a user-written FORTRAN subroutine and used for the solution.
