| Abstract: | In this paper,it is provided that the stress and strain of a main reflector with uniform pressure support (such as steel belt) by means of FEA.Then the RMS of the deformation of the reflector surface is calculated with optimization method.At last,the optimal support angle,with this angle the RMS of the deformation is the least,is given here. |

| Keywords: | Optimization method Uniform support Reflector deformation |
