WebbAbstract. In this paper, the relevant working principle of "FAST" Chinese Eye is studied, and a mathematical model is established to solve the equation of the ideal paraboloid. The ideal paraboloid model is obtained by rotating the paraboloid around the axis in the two-dimensional plane. On this basis, the specific solutions of each question are discussed, … Webb7 maj 2024 · The FAST active reflector includes a main 500 meter aperture cable mesh composed of approximately 7000 strands of steel cables, reflecting elements, actuators, ground anchors, perimeter beam, wind-shield wall, noise-shield wall, etc. The reflecting element cable mesh is installed on the annular latticed perimeter beam.
