摘要

针对如何有效进行薄膜反射面天线型面精度主动控制的问题，提出了一种静电力和边界索力相结合的双向控制方法。首先，推导了薄膜反射面和薄膜控制面间距发生变化时的静电力计算公式，并给出了静电力更新流程；然后，以电极电压和边界索力为设计变量，以薄膜反射面型面精度为优化目标，建立了薄膜反射面天线型面精度主动控制模型；最后，通过两种形式温度载荷作用下的薄膜反射面天线型面精度主动控制仿真算例，验证了控制方法的有效性。

Abstract

Aiming at the problem of how to effectively control the shape accuracy of the membrane reflector antenna, a bidirectional control method combining with electrostatic forces and boundary cable forces is proposed. Firstly, the electrostatic forces calculation formulas are derived when the distance between the membrane reflector surface and the membrane control surface changes, and the electrostatic forces update process is given. Then, with the electrode voltages and boundary cable forces as the design variables, and the membrane reflector surface accuracy as the optimization objective, an active control model for the membrane reflector antenna surface accuracy is established. Finally, the effectiveness of the control method is verified by two simulation examples of active control of membrane reflector antenna shape accuracy under two forms of temperature load.
