| 摘 要： | 在空间相机主镜镜面加工过程中,磨盘与主镜间磨削动作往复运行,使主镜柔性支撑结构受到交变载荷作用,这种交变载荷会引起结构疲劳破坏.按应力-寿命(S-N)法进行疲劳寿命分析,分析结果表明,主镜柔性支撑结构的疲劳寿命满足使用要求.通过疲劳寿命仿真分析,可以有效预示光学结构在加工、运输、使用过程中的疲劳强度,减少试验次数及成本...

| Abstract: | In the course of primary mirror face of space camera being machined,milling action runs repeatly between millstones and primary mirror,which brings about the alternately changed load in the soft support structure of primary mirror.The alternately changed load can lead to fatigue destruction of the structure.Fatigue life is analyzed by S-N method in this paper,the analyzed results show that the fatigue life of the soft support structure meets the demand.The simulated analysis of fatigue life can forebode eff... |
