| Abstract: |
| The pursuit of high-performance aerospace vehicles represents the prevailing trend, with degradation of connection status posing as a ″latent threat″ to their optimal operation. Connection status detection technology serves as a crucial ″safeguard″ ensuring high-performance aerospace missions. This paper comprehensively reviews the latest research advancements in connection status detection technologies for high-end aerospace vehicles, aiming to secure their high-performance operation and safety. Initially, the significance of connection status detection in aerospace vehicles is elaborated upon, highlighting its role as a pivotal ″assurance measure″ for efficient spacecraft operation. Subsequently, the research landscape and methodologies in this field, both domestically and internationally, are meticulously analyzed from two perspectives: bolt preload detection and contact interface state detection. The paper uncovers the challenges confronting the theories and methodologies of connection status detection technologies for high-end aerospace vehicles, and delves into potential solutions and developmental trends to address these challenges. Ultimately, this work provides a theoretical foundation and practical guidance for the further advancement of connection status detection technologies in aerospace vehicles. |
