Abstract

The paper presents the analysis of ride comfort of a railway vehicle based on the results of numerical simulations for a model of a passenger car moving along a tangent track with random geometrie irregularities. The lateral and vertical rms accelerations in 1/3 octave frequency bands as wen as the weighted rms accelerations are calculated at several positions within the car body for two track sections with different track condition and for various vehicle velocities. The obtained accelerations are compared with the comfort and decreased fatigue boundaries according to the ISO 2631-1 and PN-91/S-04100 standards.
