STRUCTURAL AND DYNAMIC PERFORMANCE EVALUATION OF A GFRP COMPOSITE BOGIE FRAME FOR URBAN SUBWAY TRAINS

초록

The objective of this study is to evaluate the structural safety and dynamic performance of a composite bogie frame in order to replace the conventional steel bogie frame with a composite one of an urban subway train. The composite bogie frame was manufactured using the autoclave curing method and tested under critical load cases. Moreover, in order to estimate the weight reduction effect, the multi-body dynamic analysis was carried out. From the dynamic analysis, the running stability and the curving performance of the bogie with lightweight composite frame were calculated and compared wth the corresponding steel bogie.
