DYNAMIC RESPONSE OF FREIGHT VEHICLE SYSTEMS--A PERFORMANCE CHARACTERIZATION
This paper presents the results of performance characteristics of modern truck designs. The dynamic response of the conventional three-piece freight car trucks is discussed in detail, including the analysis of and results from field test data, and the analytic models, their verification against test data, and the use of simulated data obtained through the use of the models. A comprehensive picture of the dynamic response characteristics of the three-piece freight car truck is presented by considering four distinct and inclusive performance regimes, namely lateral stability, trackability, curve negotiation and ride quality. This performance characterization of the conventional freight car truck will form the backdrop for the presently ongoing evaluation and assessment of the response characteristics of the premium state-of-the-art freight car trucks so that the effects of design innovations on truck performance and the consequent benefits to operating railroads can be objectively assessed.
