摘要
采用单面镀铝聚酯薄膜作为基底,设计了一种通过控制静电力分布来拉伸薄膜成形的三环多电极300mm有效口径的反射镜聚光系统。通过计算所需施加分布电势,能够有效控制圆薄膜面形变化实现不同焦距的聚光。并进行了面形成形模拟和聚光模拟,效果良好。为静电薄膜反射镜影响因素的定量研究和面形控制提供了切实可行的平台。
A Membrane concentrating system is designed,in which a 300mm circular polymer coated by aluminium of one side is stretched to deflect by three annulus electrodes below.The membrane deflection can be effectively controlled for concentrating by computed potentials exerted on the electrodes.The membrane shape forming and its effect of concentrating are simulated,and the results are accepted.The designed system has laid a foundation for thorough study in electrostatic membrane reflector.
