摘要

为了适应车载平台恶劣的工作环境

设计了一种大口径刚性支撑式快速反射镜。针对车载跟瞄转台对快速反射镜的应用需求选择音圈电机为驱动器

并分别设计了快速反射镜系统的平面反射镜、驱动器、支撑基座、测量元件和机械结构。然后

应用有限元分析方法

有效地实现了平面反射镜的轻量化及支撑基座的模态分析。快速反射镜通过球型铰链实现其运动部分与不动部分的连接

主要载荷通过铰链由支撑基座间接承载

从而有效地保障了大口径快速反射镜的承载能力和环境适应性。最后

组建了伺服控制系统

并对控制带宽和指向精度进行了测试。结果显示:所设计的车载大口径快速反射镜带宽达67 Hz

方位指向精度为1.0″、俯仰指向精度为1.1″

表明控制系统稳定实用

满足车载平台的应用要求。

Abstract

To adapting to the execrable working conditions of a dynamic platform

a large-diameter Fast Steering Mirror(FSM) with a rigid support structure was designed. Firstly

the lightweight reflector

actuators

angle measurement elements

and the support structure of FSM system were designed and selected on the basis of the applied requirement of a vehicle theodolite for FSMs respectively. Then

the reflector was lightweighted and the mode of support base was analyzed by finite element method. The moving parts of the FSM were connected with static parts by a spherical hinge and its main loads were carried out by the support base through the hinge indirectly. The design allows the FSM to bear large loads and to be suitable for the poor working conditions. Finally

the control system of FSM was constituted

and its control bandwidth and pointing precision were tested. The test result shows that the control bandwidth is 67 Hz

moreover

its pointing precisions for azimuth and pitching are 1.0″

and 1.1″

respectively. These data prove that the control system is stable and practical and can satisfy application requirements of vehicle platforms.
