Outline of Final Research Achievements

Aiming at elucidation of additives containing lubrication phenomena between corrugated sliding surfaces, we established coarse-grained molecular dynamics simulations for formation, shear-induced desorption, and replenishment of adsorbed films of additives in nanoscale spacings, and simulations for the flow of lubricating oil within and near microscale contacting surfaces. Integrating the two types of simulations, we established multiscale simulations. Based on the knowledge obtained from the simulations, we designed and synthesized a new type of additive molecules and verified its excellent adsorption performance with the quartz crystal microbalance method.

Academic Significance and Societal Importance of the Research Achievements

本研究では,ナノすきま潤滑の設計に役立つ実用性の高いマルチスケールシミュレーション法を確立した上で,高性能の添加剤分子を新規に設計・合成した.これらの成果は,文部科学省が決定した2019年度戦略目標および研究開発目標「ナノスケール動的挙動の理解に基づく力学特性発現機構の解明」に合致し,トライボロジー分野の学術発展や,自動車などに適用可能な摩擦損失を軽減する高度な潤滑技術の確立に寄与することが期待される.摩擦損失の18~40%の低減は,世界エネルギー使用量を8.7%まで削減可能と予測されており,本研究により省エネ・低炭素社会の実現に貢献できる.
