FLEXIBLE CARBODY VEHICLE MODEL--USER'S MANUAL, VERSION 2

A Mathematical Model "Flexible Carbody Vehicle Model" was developed in Phase I of Track Train Dynamics Program to simulate dynamic behavior of a conventional freight car equipped with constant column damping in trucks. This model is the second version of this model and includes the option for (a) constant column damped truck (b) variable column damped truck and (c) Swing Motion truck. The auxiliary snubbing devices of five types located below and/or above the bolster can be simulated. The dynamic behavior of a freight car can be studied on tangent or curved track in presence of various track perturbations. The critical component loading situations can be determined under different operating environments to improve the design and enhance the safety in operation and maintenance.
