We analyze lubricant viscosity using the non-equilibrium molecular dynamics simulation. We construct the analysis technique of the viscosity of the polyolester oil by fitting the velocity function of the Poiseuille flow. In order to investigate the structural dependence of viscosity, two constrained models are introduced. Their molecular potentials are artificially changed. They show obviously different viscosity from that of the original molecular model. We consider this effect comes from the characteristic structure of the lubricant molecule. Especially, we found that structure relates to the core-like structure formed by the active groups in the polyolester oil.
