摘　　要：根据反射镜轻量化的要求,从材料的选择、轻量化结构形式的确定以及支撑结构的设计三个方面对某机载IRST系统椭圆形扫描反射镜进行轻量化设计。经有限元分析表明,所设计的扫描反射镜在谐振频率、旋转变形、热变形等方面均能满足使用要求,结构设计合理可行。According to the miniature requirement of an infrared search and track system（ IRST）, a scanning mirror for the airborne system was designed. The design effort includes material selection, lightweight structure and optimal sup- port. By adopting finite element analysis technique, it shows that all the performance of the scanning mirror such as the eigen-frequency, the rotation stability and the thermal deformation meet the application requirement. It has been used in the airborne IRST.
