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.
