Abstract:

The structural thermal deformation of large-scale radio telescopes under solar thermal load cannot be measured in real-time and compensated dynamically. To solve this problem, a digital twin-driven structural thermal deformation compensation method and system is studied. Based on the fusion of measured data and simulation data, a temperature field modeling method is proposed. A simulation and prediction model of structural thermal deformation is established,and a dynamic compensation model of structural thermal deformation is built. A digital twin-driven dynamic structural thermal deformation compensation system for radio telescopes is developed. A micro-experimental model is studied to verify the effectiveness of the proposed method and system. The results show that the application of digital twin technology for large-scale astronomical equipment such as radio telescopes realizes the near real-time monitoring and dynamic compensation of structural thermal deformation. The proposed dynamic compensation method has a good time sensitivity, which helps improve the working performance of radio telescopes.

Key words: digital twin, radio telescope, mechanical structure, deformation compensation, temperature field
