COLLISION ENERGY-ABSORBING COLUMN AND RAIL CAR INCLUDING COLLISION ENERGY-ABSORBING COLUMN

摘要

A collision energy-absorbing column (1) is provided on a truss side of a rail car structure (2), and extends from an end beam (72) to a roof structure (20). The collision energy-absorbing column (1) includes a metal outer member (3) whose cross-sectional shape is concave or hollow, and a reinforced-plastic inner member (4) provided along the inner circumference of the outer member (3) and extending parallel to the outer member (3). The outer member (3) has two column halves (6) which extend along the column axis of the outer member (3) and are joined in the direction perpendicular to the column axis. The joined portion of the column halves (6) extends along the column axis. The outer member (3), the end beam (72), and the roof structure (20) are fastened together by a fastening member. The inner member (4) extends from the end beam (72) to the bottom portion of the roof structure (20) except for in the fastened portion.
