   <abstract xml:lang="ru">
    <p>Рассмотрена процедура определения параметров контактного взаимодействия шероховатых поверхностей. При малых нагрузках имеет место дискретный контакт, при котором отсутствует взаимное влияние нагруженных соседних неровностей.  Фрактальный подход оказывается наиболее эффективным для количественной оценки параметров контактного взаимодействия шероховатых поверхностей.&#13;
Цель исследования: оценка влияния шероховатости поверхности на функциональные свойства контакта.&#13;
Задача, решению которой посвящена статья: оценка фактической площади контакта шероховатых поверхностей. &#13;
Методы исследования: компьютерное моделирование шероховатых поверхностей и их контакта.&#13;
Новизна работы: найдена фрактальная размерность DXY, характеризующая размерное распределение площадей среза неровностей&#13;
Результаты исследования: представляется возможным оценка параметров контактного взаимодействия шероховатых поверхностей в условиях пластического и упругого состояния нагруженных неровностей.&#13;
Выводы: корректная оценка ФПК требует учета ряда параметров, определяющих как шероховатость, так и особенности фрактальной структуры поверхности.</p>

    <p>The procedure for determining the parameters of the contact interaction of rough surfaces is considered. At low loads, there is a discrete contact in which there is no mutual influence of loaded neighboring irregularities. The fractal approach proves to be the most effective for quantifying the contact interaction parameters of rough surfaces. &#13;
The study objective: to evaluate the effect of surface roughness on the functional properties of the contact. &#13;
The task to which the paper is devoted: to estimate the actual contact area of rough surfaces. &#13;
Research methods: computer simulation of rough surfaces and their contact.&#13;
The novelty of the work: the fractal dimension DXY is found, characterizing the dimensional distribution of the cut-off areas of irregularities.&#13;
Research results: it is possible to estimate the parameters of the contact interaction of rough surfaces under the conditions of plastic and elastic state of loaded irregularities. &#13;
Conclusions: correct assessment of FPC requires consideration of a number of parameters that determine both the roughness and the features of the fractal structure of the surface.</p>
