• Abstract:
  Crash Energy Management (CEM) has been developed as a means to protect occupants in train-to-train collisions. As part of CEM, sacrificial crush zones are designed into unoccupied locations in cars. These crush zones are designed to deform with a lower initial force and increased average force. With such crush zones, energy absorption is shared by multiple cars during the collision, consequently preserving the integrity of the occupied areas. Figure 1 shows the final cab end crush zone design that was developed as part of the research. A similar design has been developed for non-cab end crush zones. The non-cab end design does not include the deformable load distributor or the operator’s compartment.
