摘要：
In order to make a high precision electrostatically controlled deployable membrane antenna (ECDMA), the first thing was to do a layout optimization for all electrodes using the two level optimization method of the genetic algorithm and the gradient method. Based on the optimization idea, shape parameters of an initial membrane surface were solved with given voltage, cable tension and ideal membrane surface to get an initial membrane surface with no stress. The cutting analysis was done for the initial membrane surface with no stress. Pieces of the surface were flatted to get flat cut pieces using the method of equivalent mechanics. Based on the finite element idea, flat cut pieces were spliced to obtain the initial membrane surface state. After static electric force and cable tension were exerted on, the final forming state of the theoretical spliced reflector was gained. Based on the theory mentioned above, a 0.55 m long ECDMA model was designed, a camera measurement system was built based on the software Digimetric. The shape surface precision measurement was done for the ECDMA model. It was shown that after repeated measurement and profile adjustment, its membrane surface precision reaches 0.13mm; the realizability of a high precision making is verified. © 2018, Editorial Office of Journal of Vibration and Shock.
