| 摘 要： | 提出了蜂窝结构的三面体转镜，对这种新型转镜做了结构设计，并利用3维有限元计算技术，分析了蜂窝结构的三面体铝合金转镜的力学性能。结果表明：对镜面尺寸17.325 mm、轴向长度32.5 mm的三面体铝合金转镜，在5×10 4 r/min转速下，镜面最大变形量为0.547 μm，约为原结构铝合金转镜镜面的16%，与相同结构尺寸的铍转镜镜面变形量处于相同量级；内部最大应力小于原结构铝合金转镜。

| 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． |
