Title: COMPARATIVE STUDY OF RUNNING SAFETY AND RIDE COMFORT OF RAILWAY VEHICLE
Abstract: Summary: The paper deals with the running safety and the ride comfort of a railway vehicle. It presents methods used for investigation of these essential ingredients in the assessment of the vehicle running behaviour. The present study of the running safety and ride comfort is based on the results of numerical simulations for non-linear model of railway vehicle moving along a tangent track. Importantly, the applied model takes into account lateral and vertical irregularities of the track geometry with random character. The running safety is studied according to the UIC 518 code: through the ratio of the lateral Y to vertical Q forces in the wheel/rail contact point. The lateral and vertical vehicle body accelerations, which a passenger of the railway vehicle is exposed to, are used for the assessment of the ride comfort in accordance with the ISO 2631-1 standard. It is analysed and compared how various parameters of the railway vehicle-track system affect the running safety and the ride comfort.
