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.

In the development of rail transportation, multibody simulation (MBS) is an indispensable tool. It enables efficient analysis and optimization of various aspects to enhance the quality and performance of rail vehicles and individual components. Through precise MBS models, we can simulate the vehicle behavior under diverse conditions and develop tailored solutions for your specific requirements, thereby improving overall efficiency and effectiveness.

• Precise vehicle dynamics simulation: Predicting and analyzing rail vehicle behavior under various scenarios through accurate modeling of vehicle dynamics.
• Vehicle stability optimization: Evaluating and detecting potentially unstable states to enhance safety and ride comfort.
• Realistic rail vehicle-infrastructure interaction: Considering the interactions between vehicles and the infrastructure to gain insights into the influence of track irregularities, switches, and crossings. (Wheel-to-rail-contact)
• Calculation of wind characteristics and reparation of expert assessments for the crosswind verification according to RIL807.04, EN 14067-6 and TSI HS RST.
• Proof of strength for components within the scope of approval and component analysis for optimal and safe design.
• Simulation of the clearance gauge for planning and for the determination of the vehicle gauge according to DIN EN 15273 (EBO, BOStrab, internal company guidelines).
