移着油膜による接触面圧力分布の測定法

抄録

The adhered oil film transfers from one specimen surface to another when the contact occurs between surfaces with and without very thin oil film. A transferred oil spot is in fact a real contact surface. In this paper, the real contact area and the pressure distribution of the contact surface are measured by detecting the distribution of the transferred oil film using the reflection of light irradiated onto the contact surface. The measuring device developed in this study is shown, along with the pressure distribution measured in the contact of lapped, ground, blasted surfaces and so on.
