Abstract

The variations of ambient temperature can change the state of the supporting structure of the reflector for Five-hundred-meter Aperture Spherical Radio Telescope. The purpose of this research is to monitor the temperature and the varieties to find their relationship. Firstly, the temperature monitoring system is introduced. Then, this study proposed a temperature analysis method based on the polynomial regression technique. After that, the influences of the non-uniform temperature field brings by the sunshine to the ring beam is presented. Meanwhile, the relationships between the variations of the stress for ring beam, the shape of ring beam and cable forces with temperature changes are figured out. The results reveal that the temperature field of the ring beam under sunshine is non-uniform, but the temperature difference is less than 6 . However, the seasonal temperature difference has great influence on the shape of ring beam and the force of main cables. These results provide useful support for the future monitoring and safety assessment of supporting structure for FAST.
