CRITERIA FOR EVALUATING RAIL VEHICLE DYNAMICS BY COMPUTER MODELING TECHNIQUES
The problem is tackled by means of a 14-degree-of-freedom computer model excited by two track geometry errors: a deterministic input based on bolted-rail track, and random geometry power spectra based on continuous welded rail. The model is not described, and the paper is devoted to the study of possible criteria and the results obtained from application of these criteria to various types of rolling stock. The authors review the classical ride- comfort criteria of JNR, ISO, BR and devise complex criteria combining vertical and cross vibration, and characterising: the maximum permissible weight of the vehicles; the stability of the track/vehicle system; comfort in curves; the ride quality.
