Shelter effect analysis of wind barrier on large radio telescope

With the development of radio telescopes to large aperture, high frequency and high precision, the fitting accuracy of the reflector can be deteriorated by the time-varying wind load, leading to the reduction of the telescope performance. Therefore, wind load is an unneglectable environmental factor affecting the telescope. In this paper, the feasibility of designing a wind barrier in front of the telescope to reduce the wind disturbance on the telescope is discussed, and the effect of wind barrier size parameters on reducing the wind disturbance is analyzed through orthogonal experiments. The numerical simulation indicates that the wind barrier can effectively reduce the wind pressure on the reflector surface. Orthogonal experiments suggest that the height of the wind barrier is the most significant factor affecting the shelter effect, while the width of the wind barrier ranks the second, and the length of the wind barrier has the least effect.
