摘要
根据已有的研究工作,对成像镜调焦机构系统做了进一步改进,并对模型进行了环境影响分析和考虑接触时的受力分析.文中详细给出了设计的基本原理及设计方法,该机构通过电机驱动丝杠完成对成像镜的移动.由接触分析结果可以看出,考虑接触约束时所计算得到的结果比较符合实际情况,结构的强度满足要求.
Based on the previous work, a modified model of adjustment mechanism of the imaging lens's focal length of a space solar telescope is designed. Analysis on the environment and contact ifluence of the modified model are also presented in the paper. The design principle is illustrated in the article. The movement of the image lens is controlled by the step motor and screw. According to the result of the contact analysis, the modified mechanism is workable.
