| Abstract | 本文针对新疆110 m射电望远镜天线主动主反射体结构建模及调整分析技术进行了研究.首先,将简化促动器引入QTT天线结构模型中,建立了包含简化促动器的主动主反射体结构模型;其次,在外载荷作用下,由主动主反射体结构模型可以得到变形天线的促动器指向;再次,基于促动器刚性构件假设,将主动调整分析进一步简化为面板支撑点沿促动器指向调整指定位移的有限元约束方程;最后,针对QTT天线模型对本文方法进行案例仿真,所提方法计算结果与ANSYS仿真结果的差异量约为10~(-9)mm,表明所提方法的有效性.该方法可为大型射电望远镜天线主动调整的精确分析提供参考. |
| Other Abstract | Herein, the structural modeling and adjustment analysis of the active main reflector of the Xinjiang 110-m Qitai radio telescope (QTT) are performed. First, a simplified actuator is introduced in the QTT antenna structure model, and the active main reflector structural model, including the simplified actuator, is established. Second, the actuator direction of the deformable antenna under the action of external load is obtained from the structural model. Further, by assuming a rigid actuator, active adjustment is further simplified as the finite element constraint equation where the panel support points adjust to the specified displacements along the actuator direction. Finally, the QTT radio telescope model is simulated based on the proposed method. The difference between the calculation results of the proposed method and the simulation results of ANSYS is about 10−9 mm, which indicates the effectiveness of the proposed method. This work provides a reference for the accurate analysis of the active adjustment of radio telescope antennas by the proposed method. |
