A mathematical model of a railroad freight car has been developed under the Track-Train Dynamics Program. The model simulates a car equipped with auxiliary suspension devices (e.g., rubber-cushion type or viscous dampers) under various perturbed track conditions. The study compares the model predictions with test data, and demonstrates the application of the model in studies of various auxiliary suspension devices for controlling the harmonic roll response and component loadings of a railroad freight car.
