These bogies are based on platforms to reduce design time and cost. For the design of these platforms precise and safe design loads are required that represent various operational conditions. Therefore, the goal of this work is to develop a method to determine standardised multi-body simulation scenarios for bogie platforms. For this purpose, so called representative synthetic scenarios are used due to their low simulation effort compared to the simulation of real tracks. The representative synthetic scenarios are created based on operational statistics that represent a real track. The scenarios consist of different horizontal elementary scenarios. In this work, representative synthetic scenarios were created and validated for the rail vehicle in use. Vertical elementary scenarios were integrated into the representative synthetic scenarios to also consider the vertical track layout. The standardised scenarios summarize real tracks. These tracks have not been measured with the same vehicle. The measured motor torques, and braking forces are therefore not automatically applicable to the vehicle in use. Hence, synthetic motor torques, and brake forces were created for the vehicle in use. The standardised scenarios are designed to approximate target loads that were previously defined based on various real tracks. To build these scenarios, initial standardised scenarios were created, simulated and compared with the target loads. If the target loads could not be achieved, the operational statistics were changed iteratively based on a sensitivity analysis until the target loads were approximated with sufficient accuracy. The sensitivity analysis ensured that the statistics could be modified with fewer iterations. Precise and safe design loads for rail vehicle bogie platforms can be generated using the developed standardised scenario generation method. This allows the bogie platforms to be designed for a wide range of operational conditions, while enabling a lightweight and energy efficient bogie design.
