Recent Research and Development in Railway Dynamics

Abstract

This paper introduces the latest research and development through numerical analyses and experimental tests conducted by the Railway Dynamics Division on overhead contact lines, railway vehicles, tracks and structures. This includes analyses, tests on the interaction of the overhead lines and pantographs, wheel/rail rolling contact, developments relating to the wheel load reduction control bogie and the low cost ladder sleeper based on wheel load measurements. This paper also introduces the development status of the "Railway Simulator" using advanced HPC (High performance Computing), designed to clarify dynamic phenomenon to optimize the railway system.
