| Abstract(J) | エンジン摺動面は運転により摩擦特性が変化する．このなじみ過程は，表面形状，粗さ変化と反応膜形成がスケールを横断し複合的に影響する現象であるため，モデル化が困難であり経験的理解にとどまっている．今回，表面粗さ変化と反応膜影響を同時に考慮可能なモデルを構築し，軸受なじみの定量予測を行った内容を報告する． Translation |
| Abstract(E) | Engine bearing friction characteristics change during operation as running-in progresses. Running-in is governed by coupled processes across scales, including surface geometry evolution, roughness changes, and tribo-film formation. Thus, it is difficult to model and often understood only empirically. In this study, we develop a model that simultaneously accounts for roughness evolution and tribo-film effects, enabling quantitative prediction of the bearing running-in process. The proposed approach offers improved interpretability of running-in mechanisms and provides a basis for rational design of sliding surface performance. |
