Abstract:

As the application of digital twin technology continues to expand in the field of weaponry and equipment, it, as a potentially disruptive key technology in this field, is gradually becoming a core element and an important development means for enhancing the research, development, and design capabilities of aviation weaponry and equipment. Under the development demands of economy, safety, and high efficiency in the aviation field, in-depth exploration of the connotation and key technologies of digital twin technology is crucial for clarifying the future direction of digital simulation technology in the field of aviation vehicles. This paper systematically reviews and analyzes the concept and research status of digital twin, and proposes the key technologies and application development directions of digital twin in the field of aircraft design. The aim is to provide valuable references for the digital construction of the aircraft strength system.

Key words: synchronous evolution, loading prediction, digital twin, aircraft, strength system
