| 英文摘要 | Wind field is a critical issue for radio telescope antenna structure design and observation. As the telescope performance requirements are getting higher and higher, the antenna structure design becomes more and more complicated, and the influence of wind load on antenna pointing in the observation is also serious. How to ensure the stiffness and strength of the structure during the design and to improve the effective observation time during the observation all need accurate wind field data. Due to the traditional wind tower setup method cannot quantitatively evaluate the reliability of the setting point position, so a method based on numerical simulation to optimize the position of the wind tower is proposed. The boundary conditions of numerical simulation are set based on specification parameters, the overall trend is consistent with the measured data, and therefore the simulation accuracy could meet the requirement. Four wind tower positions were set at the test site. According to the simulation results, the root-mean-square error (RMSE) of wind speed between point P2 and the antenna position is the smallest. So, the measured data in P2 could better represent the wind field characteristics of the antenna area. |
