Digital Twin-Driven Structural Thermal Deformation Compensation System for Radio Telescopes
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.
