Research on Digital Twin System of Large Aircraft Ground Dynamics Test Platform

The large aircraft ground dynamics test platform is a significant research infrastructure to test and simulate the ground dynamics characteristics of aircraft. However, there exist many problems in physical experiments and traditional model-based virtual experiments of this platform. Here we introduce the emerging digital twin technology to fully expand its comprehensive verification capabilities and enhance the digitized development level of the large aircraft ground dynamics systems. Firstly, the technical requirements of the digital twin system for the large aircraft ground dynamics test platform are analyzed, and its schematic design is completed. Then, a four-tier technical architecture including physical object, data network, digital twin and application scenario is constructed. An in-depth analysis of this digital twin system focusing on its potential research and application scenarios for aircraft ground dynamics is illustrated. Finally, the key technologies of digital twin construction and evaluation, as well as high-performance virtuality-reality hybrid networks are elaborated and analyzed, providing a certain basis for subsequent specific design and development.
