| 摘 要： | 以静电陀螺仪为核心部件的静电陀螺寻北仪是一种高精度的寻北仪器，其中静电力干扰是主要干扰源之一。本文针对静电陀螺寻北仪中的静电力干扰进行仿真分析。图形仿真结果直观地表明了转子的二次谐波、三次谐波，沿ｘ轴、ｙ轴相对电极的面积差，沿ｘ轴、ｙ轴的电极错位以及转子中心相对电极中心的偏移对干扰力矩影响的性质及大小。仿真结果可作为结构及系统设计的参考。

Emulation analysis on electrostatic disturbing torque to ESG north finder |
| |
| Abstract: | An ESG (electrostatic suspended gyroscope) north finder, in which ESG is key element, is a high precise north finder. The electrostatic disturbing torque is one of main disturbing torques. Emulation analysis on electrostatic disturbing torque to ESG north finder is presented. According to the emulation, the effect of the second and the third harmonics of rotor, the effect of area difference of a pair electrodes along x axis or along y axis, the effect of the stagger of electrode along x axis or y axis and the effect of the deviation of rotor center from electrode center are shown. This result would be a reference for mechanism and system design of the ESG north finder. |
