通过建立合适的惯组测量坐标系,构建了惯组内部惯性器件敏感轴和惯组测量坐标系之间固定的相对关系,实现了惯组在六面体测试工装内每次标定的误差模型系数均反映同一个映射关系,实现了惯组重复安装标定时惯组误差模型系数的统一计算、对比,对方便工程使用、有针对性地改善惯性器件性能有着重要的意义。
By establishing a suitable coordinate system for measuring the inertial mass, a fixed relative relationship between the sensitive axis of the inertial mass inertial device and the coordinate measuring system of the inertial mass is established, and the error model coefficients of each calibration of the inertial mass in the hexahedron test fixture are reflected The same mapping relationship achieves the uniform calculation and comparison of the coefficients of the inertia error model during the repeated installation and calibration of the habitual assembly. It is of great significance to improve the performance of the inertial device for the convenience of the engineering.
