PROGRAMMING DOCUMENTATION, DETAILED TRAIN ACTION MODEL

The detailed longitudinal train action model computer program analyzes longitudinal (only) behavior of a train, both as a whole and car by car. This is done by modeling a train as though it were a mass-spring like system. Masses of the system are considered to be the vehicles, unless sliding sills are employed, in which case each such equipped vehicle is considered to be composed of two masses, its sill and its body. Forces on each vehicle (or, if sliding sills are employed, each vehicle body and sill) are then identified and quantified. Newtonian equations of motion are written to provide a system of simultaneous (generally nonlinear) ordinary differential equations. Several forward integration schemes are described. This report represents the Programming manual documentation for the Detailed Train Action Model.
