| Abstract: |
| According to the work mode and environment requirement of airplane platform, t
he process of an air-borne 0.45 m satellite communication antenna structure desi
gn is discussed, involving the optimization of weight, dimensions, stiffness and
strength for the antenna′s key structural parts.Mechanics calculation and simu
lation analysis of FEA(Finite Element Analysis) to the antenna structure model i
s
performed, and the result is confirmed by experiment. The results show that all
properties of the optimized antenna′s structure components meet designed requi
rements. The conclusion can be of great significance to other airborne antenna s
tructure design. |
