On strength computation, the finite element models of rotating mirror were established according to the real structure of the mirror, and the rotating three-faced beryllium mirror were analysed. Results display that the surface deformation magnitude of the mirror is approximately 0.3346 μm, and the maximum stress is 0.204 GPa at 600 m/s of edge linear speeed. The regions of maximum stress are on the axial hole and symmetric to symmetrical planes of mirror body, and keep beelines to surfaces. On the modal analysis, the results show that the first and second modals of bending vibration exist around 3.4×105 r/min and 6.6×105 r/min, which appear binate and orthogonal respectively, and another modal belongs to the first torsional vibration that occurs by 5.13×105 r/min.
