Measuring of running resistance of model wheels passing through in granular material

Abstract

Railways running in the Tokyo metropolitan area have the problem that snowfall and snow accumulation can cause disruptions to timetables. In order to solve this problem, the mechanism of the running resistance force acting on wheels rolling through granular material is investigated using a scale experimental running resistance meter. Results of previous studies have shown that a rolling model wheel generates a greater running resistance force than a non-rolling plate. In this report, the running resistance force acting on the non-rolling model wheel is measured and compared with the result of previous studies.
