ANALYSIS OF RAILCAR-SHIPPING CONTAINER SYSTEM RESPONSE TO IMPACT CONDITIONS

An existing mathematical model for simulating railcar-container system response to coupling impacts was revised to simulate configurations that were tested in full-scale experiments. The structural model is represented with the lumped-parameter technique. The resulting equations are linear except for those for the coupler forces experienced during the impact. Results from the mathematical model are compared with load and acceleration data obtained during the full-scale tests. The model predicts actual response accurately enough to make it useful as a design and safety analysis tool.
