中文摘要:随着工业4.0技术的发展,数字孪生技术正在不断渗透到工业生产和新产品研发的各个领域,并为新产品研发带来综合性能整体优化、研发成本降低、研制周期缩短等优势,是提升新产品市场竞争力的重要手段。在现代民用飞机研发过程中,从型号需求、初步定义、详细设计、生产试制、试飞取证和运营维护等产品全生命周期内,都可以利用数字孪生技术,实现虚拟和物理的无缝对接,尤其在飞机设计验证方面,更可以做到更优、更广、更快、更省。然而,在我国民用飞机研制项目中,还未形成数字孪生应用体系。本文通过对飞机架构模型设计、多模型构架集成以及模型参数辨识和验证几个方面,对数字孪生技术在飞机设计验证过程中的应用技术进行了探讨。经研究发现,数字孪生技术对飞机型号研制各阶段的设计验证,尤其是集成试验验证提供了重要的指导作用和技术支持,为民用飞机适航验证和运维服务提供了更快、更经济、更强有力的支持与保障。
英文摘要:With the development of Industrial 4.0 technology, digital twin technology is constantly penetrating into all fields of industrial production and new product development, and is bringing advantages such as overall optimization of comprehensive performance, reduction of R&D cost and shortening of R&D cycle for new product development. It is an important means to enhance the market competitiveness of new products. In the process of modern civil aircraft research and development, digital twin technology could be used to realize virtual and physical seamless docking in the whole life cycle of products such as requirements, preliminary definition, detailed design, manufacture, flight test, certification and maintenance, especially in aircraft design verification, it can achieve better, wider, faster and more economical. However, the digital twin technology has not yet been used in the civil aircraft development project in our country.In this paper, the application of digital twin technology in aircraft design verification is discussed from several aspects, such as aircraft architecture model design, multi-model architecture integration, model parameter identification and verification. It is found that the digital twin technology could provide important guidance and technical support for the design and verification of aircraft model development at all stages , especially for integrated test and verification, and also provide faster, more economical and more powerful support for civil aircraft airworthiness verification and maintenance services.
