Recent Developments in Vehicle Structure Technology

Abstract

In the fiscal year 2015, RTRI conducted research into around 300 themes. Among them were about 45 dealing with rolling stock, covering a wide range of practical areas such as increasing train running speeds and improving ride comfort, applied research such as running stability and vehicle crashworthiness, and finally, basic research such as elucidating the mechanisms underlying wheel wear.
This paper introduces three of these themes, namely, "A new type of bogie for reducing the risk of derailment," "Carbody safety evaluation method for reducing passenger injury in the event of a level crossing accident" and "Small and low-cost pneumatic centering cylinder for tilting vehicles."
