航天器快速展开机构动态角度测量方法

Dynamic Angle Measurement of Expanded Mechanism in Space Vehicle

为在地面试验中获取航天器快速展开机构的动态旋转角度,提出以测量位移数据结合几何关系计算的解决思路;对靶线通断法、拉线位移法、三角激光法和高速摄像法四种方法的特点逐一梳理,分别总结出地面试验的适应性技术方案和试前注意事项;通过4种方法的优缺点分析和试验数据对比,归纳了应用于试验的参考意见。

In order to obtain the dynamic rotation angle of the spacecraft expanded mechanism in the ground test,a solution of measuring the displacement data combined with the geometric relationship calculation was proposed.Based on target wire method,cable-extension displacement method,laser triangulation method and high speed camera method,the technical scheme and details for dynamic angle measurement were put forward.Making a comparison of advantages and disadvantages of four methods,references for dynamic rotation angle experiment were suggested.
