Abstract
An alternative FEM algorithm of fi nding piston ring
pressure distribution to a contact simulation is introduced. The
method is basing on an analytical determining of required nodal
displacement boundary conditions. Its several confi gurations
are tested using APDL and compared to a no-separation contact
simulation of a simple 2D fi nite element model of a two-stroke
piston ring made of Titanium alloy. Each of the methods tested
in the paper brings displacement result and Huber-Misses equivalent
stresses close to each other. However, only one of those
brings resulting contact pressure close to a no-separation contact
simulation. Nonetheless, the obtained confi guration occurred
to be less computationally effi cient than no- separation contact
simulation performed in an ANSYS software.
