Abstract(in Japanese) (See Japanese page)
Abstract(in English) In railway signalling systems, track circuits based on an electrical shunting principle are used to detect the presence of a train within a particular track section. An increase of contact resistances between rail and wheel makes the detection difficult. In order to detect trains surely, it is important to investigate the phenomena of the electrical contact. The contact resistances may behave like semiconductors. However, the mechanism underlying the semiconductivity has not yet clarified, so I have attempted to estimate the microstructure of wheel-rail contact surface by using a device simulator. In this paper, I hypothesize a model for the microstructure, and show its qualitative appropriateness by device simulations.
