DYNAMIC ANALYSIS TO ESTABLISH NORMAL SHOCK AND VIBRATION OF RADIOACTIVE MATERIAL SHIPPING PACKAGES

A new calculation sequence was developed to simulate the behavior of the coupler subsystem for the cask-rail car (hammer car) and the lead car in the group it impacts (struck car) during humping operations. This new coupler submodel simulates the hysteresis-type behavior of friction draft gears. Friction draft gears consist of springs and dampers in parallel rather than the series arrangement upon which the previous calculation sequence was based. Results from this submodel compare well with experimental results for friction draft gears in their "active" state during impact (before bottoming out and during recoil). This coupler submodel will now be incorporated into the full cask-rail car model.
