| Summary: | The article is devoted to one of the important problems of
increasing the wear resistance of tribosystems by applying
an antifriction polymer composite coating containing
a groove that operates in a hydrodynamic mode to the
tribocontact surface. Based on the equation of the flow of
truly viscous liquid for a «thin layer» and the continuity
equation, a self-similar solution is found taking into account
the groove and without taking into account the groove,
as a result, the velocity and pressure fields in the groove and on the surface of the polymer antifriction composite
coating are determined, as well as the load capacity and
friction force allowing to determine the increase in wear
resistance; an increase in duration of the hydrodynamic
regime. The results of numerical analysis of the obtained
theoretical calculation models and experimental evaluation
of the proposed design are also presented in order to verify
and confirm the effectiveness of the obtained theoretical
models. |
