| 摘要： | The Federal Railroad Administration has been conducting research on occupant protection in train collisions. As part of this research, computer simulations have been performed, passenger seats have been sled tested, and two full-scale collision tests of rail passenger cars have been conducted. The passenger equipment collisions tests that have been performed to date are: (1) Single car impact into a fixed barrier at 35 mph. (2) Two coupled car impact into a fixed barrier at 26 mph. As part of these tests, the cars were instrumented to measure the deformations of critical structural elements; the vertical, lateral, and longitudinal deceleration of the carbody and trucks; and the suspension displacements. The cars were also equipped with instrumented anthropomorphic test devices (test dummies) in three interior arrangements: (1) Forward-facing unrestrained occupants seated in rows, compartmentalized by the forward seat in order to limit the motions of the occupants. (2) Forward-facing restrained occupants with lap and shoulder belts. (3) Rear-facing unrestrained occupants. This paper describes the vertical and lateral motions of the cars during the two-car impact test, and discusses their influence on the responses of the instrumented dummies. |
