• Abstract:
  A Crash Energy Management (CEM) cab car crush zone ; design has been developed for retrofit onto an existing Budd ; M1 cab car. This design is to be used in the upcoming fullscale ; train-to-train test of a CEM consist impacting a standing ; freight consist of comparable weight. The cab car crush zone ; design is based upon the coach car crush zone design that has ; been previously developed and tested. ; The integrated system was developed after existing national ; and international CEM systems were reviewed. A detailed set ; of design requirements was then drafted, and preliminary ; designs of sub-assemblies were developed. The preliminary ; designs were analyzed using detailed large deformation finite ; element software. Performance of the cab car crush zone under ; ideal and non-ideal loading conditions was analyzed prior to ; development of the final design. ; The key components of the design include: a long stroke ; push-back coupler capable of accommodating the colliding ; locomotive coupler, a deformable anti-climber to manage the ; colliding interface interaction, an integrated end frame on ; which the deformable anti-climber is attached, a set of primary ; energy absorbers designed to crush in a controlled manner ; while absorbing the majority of the collision energy, and a ; survivable space for the operator which pushes back into an ; electrical closet. ; The cab car crush zone is designed to control both lateral and ; vertical vehicle motions that can promote lateral buckling of the ; train and override of the impacting equipment. The design is ; capable of managing the colliding interface interaction with a ; freight locomotive and passing crush back to successive crush ; zones. Detailed fabrication drawings have been developed and ; submitted to a fabrication shop. In addition, existing Budd M1 ; cars are being prepared to receive the retrofit components.
