THE DEVELOPMENT OF ANALYTICAL MODELS FOR RAILROAD TRACK DYNAMICS

A renewed interest during the past decade in high-speed rail transportation has underlined a need for better understanding of the dynamic interaction between vehicle and track. Speeds in excess of 160 km/h tax the presently used rail-tie-ballast track structure in terms of long-term stability and required track accuracy. Hence, the investigation of improved structures with better dynamic response characteristics and greater stability has followed in the wake of improved high-speed railcar design. This paper presented some recent developments in analytical modeling of railroad track structures for the study of vehicle-track dynamic interaction by computer simulation. Field measurements taken on main-line track of several North American railroads were used to evaluate the accuracy and define the necessary modifications of the computer model. Predictions of better overall system response and long-term stability from this computer model have aided in the preliminary design of several new track structures which are currently undergoing field evaluation.
