DRAG REDUCTION DEVICE BETWEEN CARRIAGES OF HIGH-SPEED MOTOR TRAIN SET

摘要

A drag reduction device between carriages of a high-speed motor train set is used for damping air drag. The device has a side windscreen (1) arranged on each side edge of an end wall of a carriage body (7). The side windscreen (1) is composed of a bar rubber capsule (5) and a capsule frame (4) whose shapes are matched with the curve of the side edge of the end wall of the carriage body (7). The rubber capsule (5) is connected with the end wall of the carriage body (7) through the capsule frame (4). The device is simple in structure, convenient and quick to install. And the device effectively reduces the air drag resulting from the impact of the airflow on the end wall of the carriage body (7), and improves the running speed of the train.
