摘　　要：石英音叉陀螺仪的角速度零偏中包含静电耦合、力耦合、阻尼耦合和通过相位误差泄露的正交耦合等误差,减小误差项是提升石英音叉陀螺仪性能的重要途径。本文分析了石英音叉陀螺仪的主要误差项的成因、来源和数学模型,提出了一种从零偏中分离出力耦合误差的方法,通过建模仿真和产品实测验证了误差分离方法的有效性和可行性,对后续石英音叉修调和同类工作原理陀螺仪误差分离提供参考。The bias of quartz tuning fork gyroscope is composed of electrostatic coupling,force coupling,damping coupling and quadrature coupling leaked through phase error.Reducing coupling error is a essential way to improve the performance of quartz tuning fork gyroscope.The causes,sources and mathematical models of the coupling errors in quartz tuning fork gyroscope is analyzed.A method is proposed to separate force coupling from bias.Through simulation and measurement,the effectiveness and feasibility of the error separation method is verified,which provides a reference for subsequent quartz tuning fork modification and similar working principle of gyroscope error separation.
