Abstract:There is currently an active program within the United States to improve the passive safety of train systems. In particular, the Volpe Center is supporting the Federal Railroad Administration’s research that includes numerous analytical studies and laboratory tests. The Center is managing a series of full-scale passenger car collision tests. Three tests of
conventional equipment have been completed, and two other tests are planned for the spring. After completion of these tests, the next phase will be to carry out full-scale collisions of passenger cars equipped with modern crashworthiness features, such as an integrated crash management system. Such systems, incorporating crush zones in vehicle ends, have been applied to passenger cars around the world, and have been shown to be highly effective in protecting car occupants from injury in a collision.
The objective of the work reported here is to develop a detailed final design of a crash energy management system that can be installed into an existing passenger coach car and subjected to a full-scale collision test. Elements in the program are to develop and evaluate strategies for the proposed system, prepare and analyze a preliminary design, fabricate and test critical components of the design, and finalize the design in the light of test and analysis results. The end product will be detailed drawings for a design ready to be fabricated and installed on the selected test vehicle.
