| 摘 要： | 建立了40 m口径射电望远镜天线结构有限元模型,依据模型分析结果,对40 m口径射电望远镜天线主面误差进行了分析和数值计算;从误差修正的角度,分别对主面误差的最佳拟合修正、安装角预调的工作仰角综合修正进行了分析与数值计算．误差修正后的计算结果表明,主面精度得到了大幅度的提高．分析结果为该望远镜天线的实际建造提供了参考． |

| Abstract: | Reflector error of 40m-diameter radio telescope is analyzed according to displacement datum obtained by mechanical analyses of 40m-diameter radio telescope structure. Prom the point of view of error correction, reflector dynamic error correction is discussed and calculated by applying the techniques of the best-fitting surface and rigging adjusted. The result shows the error of reflector is fallen distinctly by these corrections. These calculations and analyses provide theoretical bases for 40m-diameter radio telescope engineering. |
| Keywords: | astronomical facilities and technique 40m-diameter radio telescope error correction best-fitting surface rigging adjusted |
