The freight car hunting program predicts the critical velocity at which oscillations become unstable. It also provides information about mode shape and frequency of the oscillations. By mode shape, it is meant the relative magnitudes of the component's motions. Input to the program consists of physical constants characterizing the suspension elements of the freight car and the railwheel interaction, a velocity range that is to be investigated, and the program options that tailor the output for different needs. One of the uses of this program is a design tool. By varying one parameter of the suspension system, it is possible to study its influence on the critical speed of hunting. This report represents the user manual documentation for the Freight Car Hunting Model.
