EVALUATION OF NON-LINEAR FLEXIBLE CARBODY VEHICLE (FREIGHT CAR) MODEL

The Non-linear Flexible Carbody Vehicle Model, that was developed to study the dynamic behavior of a freight car travelling on tangent track, was evaluated using field test data. A description of the model, data acquisition and data reduction for validation is presented. Five car configurations, corresponding to different auxiliary suspension devices, were used for comparisons between the model results. While a good correlation was obtained for some configurations, it was found that better data on the characteristics of some devices is still needed.
