Lightweight body-frame of double-decker train applied to composites and aluminum extruded panels

摘要

The present invention relates to a lightweight body frame of a double-deck train. The lightweight body frame of the double-deck train is characterized by including an upper module including an upper part of the double-deck train including the body frame manufactured with composite materials; a lower module including the lower part of the double-deck train including the body frame manufactured with aluminum extruded materials; and a ceiling frame module formed in a boundary unit of the lower module and the upper module to be parallel to the bottom of the lower module. The lightweight body frame of the double-deck train to which the composite materials and the aluminum extruded materials are applied can efficiently reduce weight of the body frame of the double-deck train.
