PRELIMINARY RESULTS CONCERNING ON EXPERIMENTAL
DETERMINATION OF THE ROLLING FRICTION COEFFICIENT
The authors, in their preliminary investigations [xxxx], conceived an
original testing bench, in order to establish the magnitude of the rolling friction
Involving the mentioned testing bench, the authors started to perform
some preliminary experimental investigations in several tribo-couples, foreseen
with thin plastic cover layer.
In the described investigations, the authors offer useful correlations
between the thickness of the layers and the magnitude of the rolling friction
Their next topic will consist in combining different tribo-couples, having
covered and uncovered elements, in order to diminish as soon as possible the
magnitude of the rolling friction coefficient.
One has to underline the fact that the proposed original methodology
will represent in the next period a high-accuracy approach in the evaluation of
the rolling friction coefficient, corresponding to different pairs of elements, which
constitute the tribo-couple.
