Rigidity Effects of Reinforcement Armatures in Composite Materials Car body for Bi-modal tram

초록

The car body for the Korean bi-modal tram, which has been developing to be propelled by CNG hybrid (series type) in Korea since 2003, was designed to consider Korean physical standard, passenger capacity (standee, seated, handicapped), arrangement of vehicle components, and bus and urban railway laws or regulations. It was also designed to have light-weight sandwich constructions (composite materials) with glass epoxy skins, aluminum honeycomb cores and aluminum inner-frames. In this paper, bending and torsion rigidity of the car body for the Korean bi-modal tram were evaluated whether reinforcement armatures in the cabin will be installed or not. Rigidities of the car body were analyzed by finite element method, which can estimate effects of reinforcement armatures in the cabin of the car body.
