| 摘要： | Crash energy management (CEM) is a type of equipment design that is intended to protect occupant space during a collision. Structures at the front and back of each car act as crumple zones that absorb the collision energy. CEM is intended to distribute the damage from a collision throughout a consist to unoccupied areas. This paper describes how factors that vary in the operation of passenger trains affect the crashworthiness performance of conventional and CEM trains. Crush and secondary impact velocity are introduced as measures of crashworthiness performance. The collision scenario selected for this study includes a standing locomotiveled freight train and a cab led passenger train with an initial velocity. The passenger train contains either all CEM or all conventional equipment, and is either a multiple unit (MU) train with no locomotive, or push-pull train. The influence of consist type (MU or push-pull,) car weight, and the number of cars in a train-to-train crashworthiness are explored. |
