A method for manufacturing a reflective surface of an electrostatically formed film

Abstract

The invention belongs to the technical field of radar antennas, and specifically provides a manufacturing method of an electrostatic forming thin film reflecting surface. The manufacturing method comprises the following steps: (1) processing and manufacturing a template; (2) cutting sector membranes and skirt membranes; (3) splicing and combining the sector membranes to obtain a spliced reflecting surface; (4) sticking the skirt membranes with the spliced reflecting surface; (5) sticking double surfaces of a rope sleeve and penetrating through a rope; and (6) hanging a manufactured thin film reflecting surface. The manufacturing method is simple in operation and reliable in experience, and some difficulties in the manufacturing process of the thin film reflecting surface are fully taken into account and are displayed in detailed working procedures; the sector membranes and the skirt membranes are manufactured respectively by using cutting templates, so that the cutting precision is effectively controlled; the sector membranes are smoothly adhered to spliced templates, and the adjacent membranes are adhered in an abutting manner, so that the splicing error is effectively controlled; and meanwhile, special treatment is carried out by adopting adhesion of a circular adhesive tape strip at the center of a circle.

Description

technical field [0001] The invention belongs to the technical field of radar antennas, and specifically proposes a method for manufacturing an electrostatically formed film reflective surface antenna, and shows it in detailed procedures to realize efficient production of the film reflective surface. Background technique [0002] The working principle of the electrostatically formed film reflector antenna (ECDMA) is to apply different voltages on the film reflector coated with a metal layer and the control electrode (generally the film is an equivalent zero potential surface, and the electrode is a high potential), generating an electrostatic force on the The film is stretched so that the film forms a reflective surface with a certain focal-diameter ratio. However, its forming mechanism is very complicated. First, the film structure itself has a high degree of geometric nonlinearity; second, there is mutual coupling between the electrostatic field and the displacement field. ...

AI Technical Summary

Problems solved by technology

In 2004, SRS Technologies and Northrop Grumman cooperated to develop a 5m caliber prototype of the truly electrostatically formed film reflective surface deployable antenna, but there are few domestic researches on this technology

However, there is no specific and detailed manufacturing process for the production of the reflective surface, and there are many specific difficulties in the production of the reflective surface, so it is very necessary to be able to show the production of the thin film reflective surface in a detailed process
