| Abstract: | Based on the collimator primary mirror in vertical and vacuum, the primary mirror axial support is determined, and the support point position formula is deduced for whiffle tree structure, the flexure hinges with space curve notches is designed, and the deformation of two different primary mirror cell is analysed. The whole primary mirror component system finite element model is built, the system statics deformation and harmonic frequency is calculated. The result indicates that the primary mirror surface figure RMS is less than 0.05λ with the support structure, and the first-order harmonic frequency is reached 65.9 Hz, and all the design requirements are met. |
| Keywords: | collimator primary mirror support finite element analysis |
