光学随动系统机械分系统的精度分析

Precision Analysis of Mechanical Part of Optical Follow System

—光学成像制导仿真系统机械部分由三轴仿真转台和光学随动系统（两轴台）组成，是检测导弹导引头制导精度的重要地面设备。用两轴台形式实现的光学随动系统在国内还是首次研制。本文介绍了光学随动系统机械分系统的总体布局，分析了机械分系统可能达到的静态位置精度。

The mechanical part of optical imagery guidance simulation system is composed of three-axis simulation table and optical follow system(two-axis table),which is an important ground equipment employed to examine the accurtacy of rocket guidance device,The optical follow system attained by the form of two-axis table is initiative in domestic development,In this paper, the layout of the optical follow system is presented the possible static position accuracy,the dynamic accaracy and the natural frequencies of the mechanical part are analysed.
