Abstract:The structural characteristics and friction properties of the lubrication film of thin film lubrication were studied with n-heptane as lubricant.The method of molecular dynamics was adopted to calculate the thin film lubrication system,and the influences on the film structure and component,the slip phenomenon and the friction properties by temperature and pressure were explored.Results show that nanometer level lubricating film shows layered performance similar to solid.The higher the temperature,the stronger the adsorption of solid and liquid molecules,the greater the friction,and the interface slip is less likely to occur.The greater the pressure,the more prominent the layered structure similar to solid,the greater the friction,and the interface slip is less likely to occur.Thin film lubrication is a transition state,which can exist independently.
