Customization Design of Complex Products Based on MBSE

Aiming at the problems existing in the process of complex product customization design, such as fuzzy requirement expression and lack of effective traceability mechanism between requirement-function-structure-configuration parameters, a Model-based System Engineering (MBSE) technology for complex product customization design is proposed. Firstly, system modeling language (SysML) requirement diagram is used to express the requirement. Secondly, organic integration of multiple SysML diagrams to build configuration process model to support the design process. Then build a multi-level requirement model to establish a requirement traceability mechanism. Finally, the product instance is generated. This paper takes the high-speed train bogie as the design object, and proves that the technology can effectively ensure the explicit expression of the customization requirements of complex products, and can establish a perfect requirement traceability mechanism to provide a strong guarantee for the conceptual design and detailed design of complex products.
