棱镜组件安装误差自动化标定方法研究

Study on Automatic Calibration Method of the Installation Error of the Prism Assembly

导弹制导系统常用直角棱镜来确定惯性系统的方位敏感轴方向。直角棱镜在惯性系统上的安装误差会直接影响导弹的精确打击能力。目前的安装误差测试方法自动化程度低、费时费力、精度误差大。因此,提出棱镜组件的自动化测试方法,能减少基准传递,提高测试精度,标定精度能控制在2″(α),3″(β)。

The guidance system of missile guidance system is usually used to determine the orientation of inertial platform.The installation error of the right angle prism on the inertial platform can directly affect the accuracy of the missile.The current installation error test method is of low degree of automation,time consuming and great accuracy error.In this paper,we propose a method for automatic test of prism assembly,which can reduce the reference and improve the test precision.Calibration accuracy can be controlled in 2 "(α),3"(β).
