Abstract
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 compositebogie frame was manufactured using the autoclave curing method and tested under the critical load conditions; vertical loads andtwisting load. Through the test, the stresses at the connection region between a cross beam and a side beam and deflection weremeasured 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.
