Abstract

The aim of this paper is ride quality analysis of rail vehicles in the straight line rely on EN and UIC methods. To achieving this goal, a 9 degree-of-freedom (DOF) ride DYNAMIC MODEL of wagon has been described. The ride DYNAMIC MODEL of ERRI benchmark vehicle simulated in SIMULINK toolbox that its inputs were class 3 and 6 of USA railway. Wagon’s dynamic response versus different longitudinal acceleration has been obtained. The RIDE COMFORT INDEX calculated in MATLAB software. The results show that the RIDE COMFORT INDEX increases as a function of starting longitudinal acceleration, especially in standing passenger. The point B RIDE COMFORT INDEX (corner of wagon) is greater than point A (midpoint of wagon). This difference is very sensible in low quality track, because roll and pitch acceleration of car-body in point B are much greater than point A. At same acceleration, RIDE COMFORT INDEX value in standard method was lower than full method for standing passenger. Full method should be using for evaluation of ride comfort in metro wagon standing passengers.
