Architecture-Driven Integrated Simulation Verification for UAV System Behavior

In recent years, the complexity of aviation products such as drones has been continuously increasing. As the core element expressing system composition, functionality, and interaction relationships, system architecture plays a crucial role in system development through functions like scheme definition, interface coordination, and comprehensive trade-offs. This paper analyzes system architecture to identify key elements across different design phases, exploring a joint simulation method centered on architectural design models. By integrating multi-level interface protocols with multi-disciplinary simulation models, this approach drives the automatic generation of virtual test cases. Leveraging distributed data communication technology, it enables comprehensive cross-disciplinary system verification. Using a specific UAV landing gear system as an application case, the results demonstrate that this methodology and its supporting system can achieve cross-domain data consistency and reduce integration errors through optimized collaboration mechanisms between architectural models and simulation tools. The proposed approach provides robust assurance for the reliability and safety of UAV systems.
