• Abstract:
  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 locomotive led
  
  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.
  
  The crashworthy speed is that speed at which all of the
  
  passenger train occupants are predicted to survive in the
  
  selected collision scenario. For both conventional and CEM
  
  equipment, MU trains have slightly higher crashworthy speeds
  
  than push-pull trains. Trains with heavier cars have lower
  
  crashworthy speeds for both conventional and CEM equipment.
  
  Longer trains also have lower crashworthy speeds, although the
  
  decrease crashworthy speed is less for CEM trains than for
  
  conventional trains. In all cases evaluated, the CEM trains have
  
  significantly higher crashworthy speed than the conventional
  
  trains; the crashworthy speed of CEM trains is typically twice
  
  that of conventional trains, and in some cases is nearly three
  
  times greater.
