The paper is focused on a simulation of a railway freight wagon running on a test track with the given parameters. The railway freight wagon is running at different speeds and with different loads, at which the simulation is analysed from the point of view of derailment safety and lateral forces acting in the wheel/rail contact and individual bogies. The load distribution on the given railway freight wagon plays an important role in terms of the investigated parameters, and therefore it is compared, how the railway freight wagon behaves on the given track depending on a particular load distribution. The dynamic model was created in the SIMULIA – SIMPACK multi-body simulation commercial software. Components of a bogie were made in three-dimensional computer aided design software and subsequently were imported into the multi-body simulation software. The theoretical foundations of the forces acting on the bogie, such as the vertical load, slip, or lateral forces of the wheelset, are covered and the test track is also described. The concept of derailment safety and the forces, that are essential for these parameters, are defined. The basic parameters of the given railway freight bogie are mentioned together with its most frequent use. The article also contains a description of a three-dimensional dynamic model of a freight railway wagon. The results are evaluated and compared for each speed and load distribution. The findings will be appropriate for advancing academic research and development.
