Abstract
When major train collisions occur, train structure deforms to reduce the impact effect. However, some passengers are injured in spite of the shock absorption of the structure. Therefore, it is necessary to design train structure to reduce injuries of passengers when accidents occur. In this study, we proposed the design improvements strategies to reduce injuries of the passengers caused by train collisions. We experimented with scale-down models of passengers and vehicles. To evaluate injury levels, we used HIC36 as a standard for head injuries. As a result of these experiments, HIC36 is influenced by seating position and type. We proposed three train structures to reduce injuries of passengers. These are that of using convertible seats, seating passengers with their backs to the front of the train and seating passengers in the rear of the vehicle.
