Better Trains Through Virtual Test Drives with MBS Models

The ideal vision of rail travel? Fast, quiet, comfortable, reliable. To ensure that the passenger notices as little as possible of the rough wind outside the wagon or that goods, for example, reach their destination safely over many years of use, a great deal of development work has to be carried out long before the train comes onto the rails. In addition to comfort, safety, wear, and noise reduction play a central role.

FMD simulation of a locomotive under consideration of the relevant elastic modes

With the help of multibody simulation, new carriage concepts for modern and efficient rail transport can be optimally developed. Virtual test drives can save costly trials with physical prototypes. Based on an exact MBS model of the locomotive, wagon and wheel truck, numerous application scenarios such as, for example, a switch crossing under various driving conditions can be simulated very efficiently. Parallel to the analysis of the driving dynamics, the chassis parameters can be optimized and the wear of wheel and rail can be investigated. Simulation models are becoming more and more important in supporting the verification of vehicle technology, which can even partially be replaced.
