| 摘 要： | 在陀螺加速度计磁悬浮定中测试实验中发现，当加表处于斜置状态时，磁悬浮不能使浮子轴精确定中，浮子轴两端出现了周期性的摆动。本文分析了这一现象的产生机理，并进一步从不同方面研究了磁悬浮不能使浮子轴精确定中对加表测量精度的影响，推导了误差公式。

| Abstract: | In the magnetic suspension experiments, the effect of magnetic suspension regulation error usually causes server problems in the presence of tilted PIGAs (Pendulous Integrating Gyro Accelerometer). These problems involve periodically vibrated axes. This paper explores the mechanism behind the vibration by analyzing influence of the error, deduces the error formulas. |
