摘要	For a SiC mirror with larger thermal expansion coefficients, a passive support system for light-weighted SiC primary mirror with thermal decoupling ability was designed by combing a A-Frame flexible tangential rod lateral support structure and a mechanical Whiffletree axial support structure. To obtain the effects of the A-Frame flexible tangential rod lateral support structure on the primary mirror surface, thermal decoupling and the stiffness of the support system, the support effect of the support system was analyzed by using Finite Element Analysis (FEA) with ANSYS. And actual support system was also tested. The tested results show that the distortion error change (RMS) of primary mirror caused by the support structure is less than 13 nm in horizontal and vertical states. The worst mirror surface error change (RMS) is 1.9 nm at the ambient temperature from 14 to 23 in a laboratory. The dynamic properties of the support system including mirror are also tested. The first natural frequency of support system is 52.7 Hz and the same analyzed result is 63.0 Hz in theory. Moreover, the first six vibration modals are consistent well in both theoretical and experimental results. Finally, it concludes that this support system has excellent support effect and shows both good stiffness and thermal decoupling capability. , 2015, Chinese Academy of Sciences. All right reserved.
