PROGRAMMING MANUAL. LOCOMOTIVE TRUCK HUNTING MODEL

The locomotive truck hunting model can predict the critical velocity at which oscillations become unstable. It also provides information on the mode shape and frequency of the oscillation. The mode shape describes the relative magnitudes of the components' motions. Input to the program consist of physical constants characterizing the locomotive suspension and rail-wheel interaction, the velocity range to be investigated, and options to select the form of output. This program may be used as a design tool by investigating the influence of the parameters on the critical hunting speed. This report is the programmer's guide, which documents the numerical techniques and the control of the data processing involved in the Locomotive Truck Hunting Model. It also describes the necessary operating requirements of the program.
