Abstract:The Government and industry have a common interest in
improving the safety performance of railroad tank cars carrying
hazardous materials. Research is ongoing to develop strategies
to maintain the structural integrity of railroad tank cars carrying
hazardous materials (hazmat) during collisions.
This paper describes engineering studies on improved tank
car concepts. The process used to formulate these concepts is
based on a traditional mechanical engineering design approach.
This approach includes initially defining the desired
performance, developing strategies that are effective in meeting
this performance, and developing the tactics for implementing
the strategies. The tactics are embodied in the concept. The
tactics and concept evolve through engineering design studies,
until a design satisfying all of the design requirements is
developed. Design requirements include service,
manufacturing, maintenance, repair, and inspection
requirements, as well as crashworthiness performance
requirements.
