Requirement Oriented MBSE Approach for Next-Generation Electrified Rail Vehicles

This paper presents a methodology for the systematic, requirements-oriented development of new passenger rail vehicles using MBSE. The application example focuses on the implementation of drive systems with electric battery storage, with the objective of reducing CO* emissions on branch lines. The customer requirements, in particular with regard to range and track profile, are recorded in the SysML model. A bidirectional interface between CAD and SysML models, developed in Python, allows for the automatic determination of optimal parameters, for example in terms of capacity and weight distribution, for vehicle development. The CAD models are configured from the SysML model.
