基于模型的水下无人航行器设计方法OA

[Objective]With the increasing diversification of application requirements for unmanned under-water vehicles(UUVs),traditional design methods centered on text-based documentation have revealed nu-merous limitations in practice,such as scattered design documents,difficulty in maintenance,and low itera-tion efficiency among systems.Therefore,it is necessary to introduce a novel overall design methodology.[Method]In this study,the model-based systems engineering(MBSE)methodology was in-corporated into the design process of UUVs and integrated with traditional design approaches to establish a model-driven design and verification framework.Using the M-Design collaborative research platform,graphi-cal system modeling language(SysML)was employed to construct a comprehensive system model,including the requirements model,logical architecture model,and physical architecture model,thereby forming an inte-grated design framework.To further validate the feasibility of the framework,multi-system co-simulation technology was adopted,and a distributed simulation platform was developed to perform performance simula-tion and verification for typical mission scenarios of UUVs.Based on these efforts,a conceptual scheme for an agile design and verification prototype system has been proposed to support agile development requirements.[Results]The results demonstrate that the model-based design methodology can significantly improve the design efficiency and verification capability of UUVs,enabling a closed-loop development pro-cess from requirements definition to design implementation.[Conclusion]The proposed design methodolo-gy provides effective guidance for the design and specification verification of various manned and unmanned underwater platforms.
