Einfluss der Gleisqualität auf die Fahrzeug-Fahrweg Interaktion

摘要

The research presented in this dissertation has practically and numerically analyzed the influence of track quality parameters including track geometry, track stiffness and damping to the performance of vehicle-track interaction by online data from field measurement and co-simulation models of Finite-Element-Method (FEM) and Multi-Body-Simulation (MBS). An innovative track quality evaluation method is introduced with the help of Energy Spectral Density (ESD) distribution of the simulated dynamic wheel load.
