| Abstract: | Aimed at the separated status of structural design and electrical design in antenna engineering, CAD/CAE integrated modeling technology and antenna com- posite structure theory were studied deeply, and PO method based the displacement field of distorted reflector was used to calculation the far electric field of reflector antennas. The mechatronic analysis system for large reflector antennas was developed with some solved special difficulties including the composite structure mesh auto-partition. This system can assist the structural designers to modify the structure parameters, shape and distribution and give the requirements about the processing and manufacturing precisions. Its application can improve the design level and reduce the design cost of reflector antennas. |
