Dynamic Characteristics of Composite Materials Body for Bi-Modal Tram
The car body of the bi-modal tram has been designed and built to have low floor to provide the old and the handicapped with easy access considering Korean physical standard, passenger capacity (standee, seated, handicapped), and bus and urban railway regulations in Korea. The car body has been composed of composite materials (light-weight sandwich constructions) with glass epoxy skins, aluminum honeycomb cores and aluminum inner-frames. This paper was aimed to evaluate dynamic characteristics of the car body while the bi-modal tram was running in the test track. Based on the results from vibration accelerations measured on the floor level of centers of car bodies and axle, dynamic characteristics of the composite materials car body were discussed in this paper.
