The Structural Optimization of the 110-Meter Aperture Reflector Antenna in Multi-Levels and Multi-Working Conditions

Abstract:

The nonlinear Sequential Quadratic Programming algorithm is adopted to optimize the large reflector antenna with 110-meter aperture. Firstly, an initial finite element model of the antenna is built with the parametric programming language APDL in ANSYS. Then, taking into account of two levels in size and shape and two working conditions in zenith and horizon, the structural optimal model is given with surface precision as the goal. Finally, a better structure satisfying the design requirements is obtained through the structural optimization in multi-levels and multi-working conditions.
