研究的大角速率动调陀螺仪 ,挠性支承在所有方向上均具有有限刚度。因此 ,即使平衡环及转子不存在安装误差和其质点相对原点的位移 ,但是由于挠性轴在所有方向上均存在有限刚度 ,仍会引起陀螺仪轴向不平衡漂移及支承不等刚度漂移。利用广义坐标的理论 ,对动力调谐速率陀螺仪进行了运动分析 :分析了挠性支承特性对动力调谐速率陀螺仪精度的影响 ;对大角速率动调陀螺仪挠性支承的刚度及柔性矩阵进行了具体计算 ,并在此基础上对陀螺仪轴向不平衡漂移及支承不等刚度漂移进行了仿真分析。
In the study of high angular rate gyroscopic gyroscopes, flexible supports have finite stiffness in all directions. Therefore, even if the balance ring and the rotor have no installation error and displacement of the particle relative to the origin, the axial imbalance drift and the unequal support stiffness drift of the gyroscope may be caused due to the limited rigidity of the flexible shaft in all directions. Based on the theory of generalized coordinates, the kinematic tuning rate gyroscope is analyzed. The influence of flexible support characteristics on the accuracy of the power tuning rate gyroscope is analyzed. The stiffness and the flexible matrix of the flexible bearing with large angular velocity gyroscope are analyzed. Based on the calculation, the axial imbalance drift of gyroscope and the unequal stiffness drift of support are simulated.
