抄録

RTRI was involved in approximately 280 research themes in the fiscal year 2017 to 2018. Among them, 46 were related to rolling stock technology, covering a wide range of themes, in practical, applied and fundamental research, such as: the increase in train running speed and improvement of ride comfort, the applied research such as the running stability and reliability of rolling stock, and elucidation of the mechanisms leading to wheel wear. Three topics from this research and described in this paper are: "Quantitative evaluation of wheel flats affecting vehicle bogie behavior," "Development of a 3-Dimentional measurement device for wheel profiles" and "Evaluation of the running safety of railway vehicles in case of air spring deflation."
