An Optimal Strategy of Wind Field Regulation for Large Fully-Steerable Radio Telescope

The large, high-frequency radio telescopes is susceptible to transient wind load disturbances.To address this, this study innovatively proposes an optimal strategy of wind field regulation aimed at mitigating wind load effects by optimizing the structural parameters of wind regulator.First, key parameters of the wind regulator are selected through factorial design.Second, a surrogate model linking structural parameters to wind force on the telescope was established, and the optimal parameter combination was determined via the optimization algorithm.Finally, simulations incorporating the actual terrain of the telescope site are conducted for validation.Experimental results demonstrate that the optimal wind regulator reduces the structural deformation by up to 70.7% and improves pointing accuracy by up to 89.5%.This strategy provides a theoretical and engineering basis for extending stable high-frequency observation durations.
