摘　　要：在对动力调谐陀螺刚度和漂移误差分析的基础上,建立了由内外挠性接头装配后铰链所形成的十字型铰链的模型,并利用伪刚度体理论对该模型进行了分析。得出了内外挠性接头两铰链的相对位置关系对十字型铰链模型的影响曲线。通过影响曲线的分析,得出内外挠性接头铰链方位上的偏差对十字型铰链模型的刚度的影响程度,而模型刚度变化则对整个陀螺的装配精度提出了同轴以及正交的要求,对整个陀螺仪的装配和调试起到了指导作用。Based on analysis of rigidity and drift error for a Dynamically Tuned Gyro（DTG）, a cross model including an inner and an outer flexible hinges was established. The influence of the relative position of two flexible connector hinges on cross hinge model was given by analyzing the model with the Pseudo-rigid-body Model. It has been found out that the rigidity variety of the model requires a high assembly accuracy of whole gyro in coaxiality and orthogonality, which should supervise the whole assemblage and debugging technique.
