Available online at Procedia Engineering 10 (2011) 2375-2380ICM11 Structural Behaviors of a GFRP Composite Bogie Frame for Urban Subway Trains under Critical Load Conditions Jung Seok Kima*, Hyuk Jin Yoona aRailway Structure Department, Korea Railroad Research Institute, KoreaAbstract In order to replace a conventional steel bogie to a composite one, in this study, a GFRP composite bogie frame has been designed and manufactured to be applied to the bogie of urban subway trains. To evaluate the structural behavior, the composite bogie frame was manufactured using the autoclave curing method and tested under the critical load conditions; vertical loads and twisting load. Through the test, the stresses at the connection region between a cross beam and a side beam and deflection were measured and used to assess the structural safety. Moreover, the stress and strain distribution for the whole bogie frame was evaluated through finite element analysis and compared with the experimental results. ?2011 Published by Elsevier Ltd. Selection and peer-review under responsibility of ICM11 Keywords: Composites; bogie frame; subway; Goodman; GFRP1. Introduction The bogie of a railway vehicle sustains the weight of the car body, controls the wheel sets on straight and curved track, and absorbs the vibrations [1]. The weight of the bogie makes up approximately 37% of the total vehicle weight. Therefore, reducing the weight of the components making up the bogie system is essential for lightweight railway vehicle design. In particular, a bogie frame, which accounts for approximately 20% of the bogie weight, is intended to support heavy static and dynamic loads, such as the vertical load by the body of the vehicle, braking and accelerating load, twisting load induced by track twisting, and traction load. This is why it is common to produce bogie frames with solid steel (especially a freight bogie) or welded structures. Such bogie frames are rigid and heavy, weighing f
