RESPONSE ANALYSES OF A BOXCAR WITH COMPLIANT LADING FOR SEVERAL TRACK PROFILE AND HUNTING CONDITIONS

The simulation in the FRATE computer program (Freight Car Response Analysis and Test Evaluation) was modified from a flexible TOFC (trailer on flatcar) to a rigid boxcar with compliant lading. Analyses were performed to obtain the response of boxcar elements and compliant lading to several track profile and body hunting conditions. Three types of track profile irregularities were simulated: (1) a single vertical irregularity on both rails, (2) a single vertical irregularity on one rail and (3) rectified sine representations of staggered joint bolted rail. Hunting conditions were simulated by imposing sinusoidal lateral motions at the wheel rail interface. Worst case conditions resulted in wheelrail separations and in potentially damaging accelerations of the lading.
