摘　　要：短路匝式传感器带来的干扰力矩是引起陀螺仪随机漂移的重要因素之一,减小该项干扰力矩对提高陀螺精度能够起到重要的作用。本文利用电磁感应定律和磁路分析法对干扰力矩进行了推导,并通过Ansoft maxwell软件对短路匝传感器不同参数情况下的干扰力矩进行仿真分析,得出了转子转角、激磁电压和激磁频率对干扰力矩的影响关系曲线,最后合理选择参数以保证干扰力矩在精度允许范围内。该分析结果对减小短路匝传感器的干扰力矩和减小陀螺仪的随机漂移都具有一定参考价值。In view that the disturbance torque caused by the short-turn sensor may lead to the gyroscope＇s random drift and hence reduce the gyroscope＇s accuracy, the disturbance torque was deduced by using an electromagnetic induction law and magnetic circuit analyses, and the simulations for the disturbance torque with different sensor parameters were made by using Ansoft Maxwell. The influences of angle, voltage and frequency on the disturbance torque were obtained, and reasonable parameters are chosen to guarantee the disturbance torque be within the allowed error range. The analysis results provide a certain reference for reducing the disturbance torque of the shorted-turn sensor and hence the random drift of the gyroscope.
