• Abstract:
  This report is the first of four volumes concerning a study to investigate the costs and benefits of equipping locomotives with various crashworthiness features beyond those currently specified by the Association of American Railroads S-580 specification. The study includes model development and validation, design concept generation and evaluation, and prioritization of concepts. This first volume provides a description of the modeling efforts, including the development of structural damage (crush) and collision dynamics models using commercially available computer programs. Refinement and validation of the models was carried out through application to the conditions for three actual head-on collisions involving closing speeds ranging from 18 to 43 mph. The model is shown to provide a good simulation for these types of accidents.
