Mesh Mapping of Large Deployable Reflector in Mechanical - Electromagnetic Analyses

摘要

Ultra lightweight large deployable reflector antenna is gradually used nowadays in space applications. Both lightweight structures and materials are used. The relationship between the structure design and the electromagnetic performances is much tighter than other ground electric devices. This paper presents a mesh mapping method of large deployable reflector in mechanical - electromagnetic analyses. By using this method, the mechanical deformations can be precisely transformed on the electromagnetic model. It can be used to understand the relationship between the mechanical deformations and the electromagnetic performances on such a huge, complex structure.
