| 复合校准技术是武器装备型号项目中使用的高精度惯性器件校准的核心技术，能够在实验室模拟惯性器件“真实”的使用环境。本文针对在离心-振动条件下的加速度计复合校准问题，从系统中存在的动不平衡问题出发，建立了离心-振动复合模型并讨论了在顺臂安装和垂直安装下受到的加速度大小，给出了整个校准系统的不确定度分析。最后基于离心-振动复合校准装置进行实验验证，证明了本文所设计的校准装置和校准方法能够模拟真实的校准环境，提高校准精度。 |

| Composite calibration technology is the core technology of high-precision inertial device calibration used in weapon equipment type project, which can simulate the "real" use environment of inertial device in laboratory. In this paper, aiming at the problem of accelerometer compound calibration under the condition of centrifugal vibration, starting from the problem of dynamic imbalance existing in the system, athe centrifugal vibration compound model is established, and the acceleration under the arm mounting and vertical mounting is discussed, and the uncertainty analysis of the whole calibration system is given. Finally, the experimental verification based on the centrifugal vibration composite calibration device proves that the calibration device and calibration method can simulate the real calibration environment and improve the calibration accuracy. |
