基于虚拟立方镜的航天器总装精度测量新方法

New Method of Spacecraft Integration Precision Measurement Based on Virtual Cubic Prism

为解决使用常规基于真实立方镜的航天器总装精度测量方法无法测得设备在航天器坐标系下安装角度的问题,提出一种基于虚拟立方镜的航天器总装精度测量新方法。利用2个毫无关系的矢量成功构建一个虚拟的立方镜,再以其为传递基准来测量计算出被测设备在航天器坐标系下的安装角度,并进行实例仿真。结果表明:该方法已经过验证,并得到各方一致认可,可应用到后续型号的总装精度测量工作中。

For solving the problem that the conventional method of spacecraft integration precision measurement based on real cubic prism can＇t realize the measurement of the installation angles of the equipment in spacecraft coordinate system, the author proposed a new method of spacecraft integration precision measurement based on virtual cubic prism. The method constructed a virtual cubic prism by using two unrelated vectors and then used the cubic prism as the transfer benchmark to measure and calculated the installation angles of the measured equipment in spacecraft coordinate system, and an example was simulated. The results show that the method has been verified and approved by all parties, and it can be applied to the integration precision measurement of the subsequent models.
