Dynamic Behavior of Lubricant Molecules Under Oscillating Motion: Insight from Molecular Dynamics Simulations.

Understanding the dynamic behavior of lubricant molecules under oscillation lubrication is important for the development of advanced film lubrication technology. Herein, the dynamic behaviors of lubricant molecules under oscillating motion are studied by using molecular dynamics simulations. The effects of oscillation period on the film temperature, film velocity distribution, film stress and strain, and molecular orientation are investigated.
