Abstract

The invention discloses a FAST radio telescope health monitoring method. Monitoring is conducted in the radio telescope construction process and the radio telescope use process, a plurality of monitoring points are arranged on latticed columns, ring beams and a main cable network of a radio telescope, the stress and deformation state of the monitoring points are monitored, and therefore the structure safety and the use reliability of the radio telescope are monitored. The radio telescope construction process and the radio telescope use process are involved, monitoring is comprehensive, and the structure safety and the use reliability of the radio telescope can be ensured. The monitoring points are reasonably distributed on the radio telescope, and therefore the overall monitoring is achieved through the monitoring points as fewer as possible.

Description

technical field [0001] The invention relates to a method for monitoring the health of a FAST radio telescope, in particular to the structure safety monitoring of the radio telescope. Background technique [0002] The National Astronomical Observatory of the Chinese Academy of Sciences proposed to build a 500-meter-caliber spherical radio telescope, which is the world's largest single-caliber radio telescope. FAST (Five-hundred-meter Aperture Spherical radio Telescope, referred to as FAST) has broken through the 100-meter engineering limit of ground-based telescopes and created a new model for building giant radio telescopes. The overall technical indicators of FAST: the aperture is 500m, the radius of curvature of the reflective surface is 300m; the aperture of the lighting area is 300m, and the focal ratio f / D=0.4611. [0003] The FAST active reflector is composed of ring beams, lattice columns, reflector units, main cable nets, actuator devices, ground anchors, etc. The s...
