SQUEEZE-FILM LUBRICATION IN FRICTION PAIRS
Fundamental and Applied Problems of Engineering and Technology, 2021Osteoarthritis is a serious joint disease with severe degradation of cartilage tissue, which, according to the World Health Organization, is one of the ten most disabling in developed countries. Due to the poor ability of the articular cartilage to self-regenerate, the treatment of osteoarthritis is a difficult and in many cases unsolvable task, which

STUDY OF FRICTION COEFFICIENT IN STEEL/POLYSTYRENE FRICTION PAIR
Научные исследования молодых ученых. Опора России: сборник статей всероссийской научной конференции (Петрозаводск, Декабрь 2022), 2023В работе исследуется зависимость коэффициента трения скольжения от изменения в приложенной нагрузке и скорости в паре трения сталь/полистирол при сухом трении. Во время исследования частота вращения испытуемых тел имела 5 значений: 1 мин-1, 5 мин-1, 10 мин-1, 25 мин-1 и 50 мин-1, а приложенная нагрузка составляла 75 Н и 100 Н.

Frictional Characteristics of Metal Friction Pairs and the Amontons and Coulomb Friction Laws
Journal of Friction and Wear, 2019Based on the interpretation of the laws of friction of Amontons and Coulomb as equations of linear regression of the friction force on the normal pressure force corresponding to the statistical processing of the experimental results, the values of the friction coefficients for six metal pairs are calculated.

Friction and Particle-Hole Pairs
Physical Review Letters, 1984The effect induced by dissipation on quantum phenomena has recently been considered, taking into account as a starting point a phenomenological Hamiltonian in which the environment is simulated by an appropriately chosen set of harmonic oscillators. It is found that this approach should be adequate to describe the low-energy behavior of a wide class of
