摘要

测绘相机光学镜筒是保障测绘相机完成高精度测绘任务的重要部件，它的性能好坏直接影响测绘相机成像质量。为得到高质量成像相机，本文从材料选取、结构形式的确定和性能分析等方面详细阐述了测绘相机光学镜筒的设计过程。通过分析比较，最终选取铸钛合金ZTC4作为镜筒的材料，采用单镜组加筋壳结构的组合形式，并通过PATRAN/NASTRAN软件对主镜筒装配体的静力学和动力学分析得到具有很好整体性能的光机结构；同时给出了形位公差要求、拟定了严格的薄壁壳体的加工方法，并论述了单镜组和主镜筒整体装配的过程。

Abstract

Mirror lens of mapping camera is the important component

which can guarantee mapping camera to fulfill the mapping task with high precision. It’s performance will effect directly the imaging quality of the mapping camera. In order to gain the mapping camera with high imaging quality

the design of mirror lens is issued from the choice of materials

the decision of structure

the analysis of performance and so on. By compared

ZTC4 is selected as the material for mirror lens finally

and combination format is adopted that components with mirrors are assembled in the thin shell with stiffeners. Optical-mechanical structure with good overall performance is obtained though the static and dynamic mechanical analysis by PATRAN/NASTRAN. The geometric tolerance requirements are given

the processing methods of thin shell are developed

and the assembly process of one component and main mirrors lens is discussed.
