摘　　要：通过推导得出力矩反馈速率陀螺仪的主要性能参数等效阻尼比及等效转动惯量与陀螺表头增益及时间常数有关。针对某力矩反馈速率陀螺仪设计了再平衡回路,试验确定了不同输入频率下陀螺表头参数的变化趋势,从而得出陀螺的主要性能参数阻尼比及转动惯量在整个频段内的变化趋势。解决了陀螺仪性能参数在使用中不准确,从而影响回路设计的问题,为力矩反馈速率陀螺仪的实际应用提供了依据。It deduces that the equivalent damping ratio and torsion pendulum which is the mare pertormance parameter of the torque feedback rate gyro is related to the gain and time constant of the head of meter. According to a torque feedback rate gyro,it designs the rebalance loop. The experimentation concludes the change tendency of parameter of the head of meter in different input frequency,so that the change tendency of damping ratio and torsion pendulum in the whole frequency is determined. It solves a problem that the performance parameter of rate gyro is not accurate in use, the design of loop is influenced. It provides bases for the practical application of the torque feedback rate gyro.
