Single-Panel Digital Twin Motion Based on Unity3D Large Reflective Surface Antenna Actuator

Based on the Unity3D engine, the digital twin motion of a single panel in a large reflecting surface antenna is investigated. By building a high-precision 3D model and combining the actual motion characteristics of the antenna panel, it is hoped to simulate the motion behaviour of the panel using the physics engine and animation system of Unity3D. In order to synchronise the digital twin with the actual physical system, a real-time program-driven approach is used to dynamically reflect the motion state and positional changes of the panel. The system not only provides visual support for antenna design and optimisation, but can also be used for fault diagnosis and performance prediction, providing an efficient and intuitive digital solution for the operation and maintenance management of large reflector antennas.
