卡尔当环的工艺误差包括内环和外环的静不平衡, 内环轴与外环轴及转子轴与内环轴的不相交和不垂直, 内环轴和外环轴为非惯性主轴, 即惯性积不等于零等。本文对这些工艺误差对基座不动的自由陀螺仪的漂移的影响加以探讨。讨论的结果表明, 静不平衡和各转动轴的不相交对漂移的影响是主要的, 在有章动振动的情况下, 内环的惯性积对漂移的影响和惯性矩的影响相当。其它工艺误差的影响是极小的, 因而可以略去。
The process error of the Carlton ring includes the static imbalance of the inner ring and the outer ring, the inner ring shaft and the outer ring shaft, and the non-perpendicular and non-perpendicularity between the rotor shaft and the inner ring shaft, the inner ring shaft and the outer ring shaft are non-inertia main shafts, Inertial product is not equal to zero. In this paper, the influence of these process errors on the drift of the free-standing free gyro is discussed. The results of the discussion show that the static unbalance and the disjointness of the axes of rotation are the main influences on the drift. In the case of a nutating vibration, the influence of the inertial product of the inner ring on the drift and the moment of inertia are comparable. The impact of other process errors is minimal and can therefore be omitted.
