• Abstract:
  This paper describes the results of the CEM equipped ; locomotive coupling tests. In this set of tests, a moving ; CEM locomotive was coupled to a standing cab car. The primary ; objective was to demonstrate the robustness of the PBC design ; and determine the impact speed at which PBC triggering occurs. ; The coupling speed was increased for each subsequent test until ; the PBC triggered. The coupling speeds targeted for the test were ; 2 mph, 4 mph, 6 mph, 7 mph, 8 mph, and 9 mph. The coupling ; speed at which the PBC triggered was 9 mph. The damage ; observed resulting from the coupling tests is described. Prior to ; the tests, a lumped-mass model was developed for predicting the ; longitudinal forces acting on the equipment and couplers. The ; test results are compared to the model predictions. Next steps in ; the research program, including future full-scale dynamic tests, ; are discussed.
