PRELIMINARY EVALUATION OF RAIL VEHICLES BY COMPUTER SIMULATION.

Mathematical models of rail vehicles and track structures developed over the past decade have proven to be invaluable tools in rail transportation research. One important use of these mathematical models is to provide a preliminary evaluation of new rail vehicle and track structure designs, prior to extensive prototype construction and testing. In this paper a brief description of Battell's linear, random vibrations rail vehicle model, Program TRKVPSD, is given. This program has in the past been usd for comparative studies of different freight and passenger rail vehicles.
