Abstract

Abstract

A threefaced rotating mirror with honeycomb cellular structure in the ultra-high speed camera was presented in this paper, and the mechanical traits of such a structural three-faced aluminous rotating mirror were analyzed by use of FEM. The data indicate that the ultimate deformation magnitude of the mirror surface with width 17.325 mm and length 32.5 mm is 0.547 μm under the rotating speed of 5×104 r/min which is 16% times of nonhoneycomb cellular rotating mirror, the same with the beryllium rotating mirror, and the ultimate stress in this mirror is smaller than that of the former aluminous mirror．
