本文讨论无平衡环动力调谐陀螺仪的动力学原理。应用进动理论,采用假定模态法研究弹性支承的运动,确定调谐块扭摆运动的规律,进而推出动力调谐条件。解释在载体作二倍旋转角振动情形下陀螺不产生漂移的原因,并根据具体数据给出了数值计算结果。 This article discusses the dynamics of unbalanced ring tuned gyroscopes. Applying the precession theory, the motion of the elastic support is studied by using the presumed modal method to determine the law of the wobble of the tuning block, and then the dynamic tuning condition is derived. Explain the reasons why the gyroscope does not drift when the carrier vibrates twice as the rotation angle and give the numerical calculation results based on the specific data.
