Design and Research of Tip/Tilt Mirror in a Space TelescopeCorrelation Tracking System |
| |
| Abstract: | The design requirements of tip/tilt mirrors in correlation tracking systems and the weight reduction modes of tip/tilt mirrors are analyzed.SiC is chosen as mirror materials and three structures are designed. ANSYS is used to simulate static analysis of different designed structures in gravity field and transient dynamic analysis at 100Hz and ±0.1mrad. In order to study the relationship between ANSYS data and optical parameters easily, programs are compiled in MATLAB. Results show that the three structures meet the performance requirements of optical systems. |
