磁场系统作为磁光阱的重要组成部分，在高精度冷原子陀螺仪中占有极其重要的地位。随着陀螺体积的不断减小和集成度的不断提高，磁场系统的制造和装调误差对陀螺性能的影响不断增大。这些误差会引起磁场零点漂移和磁场梯度变化，降低捕获效率和原子团的质量，从而影响陀螺性能。从三维磁光阱磁场分布的理论分析出发，结合数学建模和计算机仿真，对三维磁场系统的主要制造和装调误差对磁场的影响进行了分析和比较，并基于预设阈值利用试验设计和数学回归对关键制造和装调参数设计了合理的容差限，为小型化冷原子陀螺仪三维磁场系统的设计和制造提供了理论依据。

Magnetic system of magneto-optical trap is an important part of high-precision cold atom gyroscopes. With the continuous decreases of gyroscope volume and improvements of integration, the effects of manufacturing and assembly errors of magnetic system on gyroscope performance are increasing. These errors will cause the field’s bias drift and gradient change, reduce work efficiency and quality of cold atom clouds, and ultimately affect the gyroscope performance. Based on the analysis of field distribution of three-dimension magnetic-optical trap and combined with the mathematical modeling and computer simulation, the effects of main manufacturing and assembly errors on the magnetic fields are analyzed and compared. In view of the present thresholds, the reasonable tolerance limits of key manufacturing and assembly parameters are designed by experimental design and regression analysis. And the theoretical basis for the design and manufacture of three-dimension magnetic system of miniaturized cold atom gyroscope is also provided.
