| Abstract | Large reflector antenna, a typical electro-mechanical system, is designed to satisfy the demands of both electrical performances and structural properties. Its characteristics very much depend on surface accuracy in traditional separate design, which is closely demonstrated by the well-known Ruze equation. Mechanical design of large reflector antenna needs integrating with electrical performances by the Mechanical-Electromagnetic-Field Coupling Model (MEFCM), and then optimizing structural variables of topology, type, shape and size under the constraints of mass and stress. In this study, on one hand, a wind and gravity load analysis of the reflector backup structure is performed at horizon and zenith positions. On the other hand, as an important part of the telescope system, the Mechanical-Electromagnetic-Wind Integration (MEWI) method is applied to structure design of a 110m diameter reflector antenna. For evaluating MEWI against traditional separate design method, simulations are needed and described in details with several interesting conclusions, drawn for applications in engineering.
