The frequency domain model computer program developed by the Truck Design Optimization Project (TDOP) simulates the operation of an idealized railroad freight car riding on standard three piece trucks. Given user specified data describing the characteristics and operating conditions of the vehicle, the program utilizes track deflection data prestored on random access disk to generate driving functions for the model. These track deflection data are broken down into frequency components before being used to activate the simulated vehicle. Similarly, the results of program execution are vehicular responses as functions of frequency. The large execution times associated with time domain models are avoided, but the price for this saving is the restriction of the simulations to those idealized conditions that are solvable by linear simultaneous complex equations.
