Research on Requirement Management of Railway Vehicle Design Based on MBSE

Model-Based Systems Engineering (MBSE) is a model-oriented system analysis method with a high degree of normalization, standardization and reusability. At present, in the process of railway vehicle design and development, there are problems such as non-uniformity, discontinuity, lack of meticulousness and non-standardization of requirements management. Railway vehicle design requirement management is an important link in the process of railway vehicle research and development, which is directly related to the quality and utility of railway vehicle products. At present, the domestic railway vehicle design requirement management is still in the initial stage of research and application, and lacks systematic method system and implementation experience. This paper proposes a railroad vehicle design requirement management method based on MBSE, which provides ideas for guiding railroad vehicle design requirement management, improving product quality and benefit, and promoting the improvement of railroad vehicle requirement management level.
