摘要
根据某空间高分辨率CCD相机的结构设计方案 ,利用结构设计软件Solidedge建立了次镜支架的结构分析模型 ,并利用有限元分析软件Vnastran对不同结构和尺寸的次镜支架进行了动力学分析计算 ,提出了次镜支架的鼓型偏置式四翼梁结构 该结构具有较高一阶谐振频率和良好的机械加工性能 。
According to the structural design scheme for a high resolution space CCD camera, the structural analysis model of bracket structure for the second mirror is established by means of the structure design software Solidedge. The natural frequency and the first three vibration modes of different types and various dimensions bracket structure for the second mirror are analyzed by means of FEA software Vnastran. Then,an offset bosomed cross structure for supporting secondary mirror is proposed. The structure has a higher resonance frequency and fine cutting property so it can be applied to large aperture space telescope.
