Abstract

Using the simulation software SIMPACK, the mechanical model of a freight car train running along a s-shaped track under high longitudinal pressure forces is presented. With the aid of simulation the freight car in the centre of the train should be judged with respect to several derailment criteria. The results are veri- fied by comparison with measurements. 1 Introduction Simulation of the dynamic behaviour becomes more and more significant for analysis, design and development of railroad systems. Recently, the simulation tool SIMPACK, [1], a computer programme with a very wide range of applica- tion (vehicles, aircraft landing gears, robots and space structures) has been enhanced by analysis and design features for railway vehicles, [2], [3]. With the aid of this tool, i
