Multi-architecture Design Method for Landing Gear System Based on Domain Specific Modeling

Aiming at the problems of unclear multi-level granularity, complex multi-stage interaction and heterogeneous multi-domain coupling of architecture models in the overall design process for the landing gear system, a domain specific modeling-based multi-architecture design method is proposed. The architecture design process of landing gear system is firstly analyzed from three dimensions, including multi-level, multi-stage, and multi-domain dimensions, then the multi-architecture design framework of the landing gear system is proposed. By fusing domain-specific modeling technology, the cognitive domain and physical domain meta-models of the landing gear system are constructed to describe the system characteristics. The model driven technology is used to calculate and verify the static technical parameters and dynamic system behaviors of the landing gear system. Finally, taking the overall-design of certain landing gear system as an example, the requirements, functional, logical, and physical architecture of the landing gear system are modeled and analyzed by the proposed method to verify the proposed method. The results demonstrate that the proposed method can improve the scalability of the landing gear system architecture design.
