Analysis of the Rail Roughness Influence on Vehicle Dynamic Behavior by Means of Multibody Simulation
Journal Title: Archives of Transport - Year 2011, Vol 23, Issue 1
Abstract
The paper presents the results of multibody simulations performed for the model of rail vehicle in order to study the influence of introduced rail roughness on dynamic characteristics of vehicle. Dynamic behavior has been assessed with the accelerations of vibrations measured for chosen points in the model of five-piece tram. Moreover there have been shown calculated normal modes and related natural frequencies of the multibody model. The influence of rail roughness has been analyzed with the tram runs performed for given speeds. Yielded results have enabled to conclude about sources and propagation of vibrations considering kinematic excitation resulting from geometric imperfections of rail.
