Abstract

Способ определения резонансной частоты трехстепенного гироскопа с упругим подвесом, включающего два канала коррекции и датчик момента, заключающийся в возмущении по моменту в одном канале коррекции за счет ввода постоянного напряжения в этот канал, измерении изменения тока датчика момента по перекрестному каналу и измерении частоты вращения ротора, отличающийся тем, что, с целью повышения быстродействия определения резонансной частоты, измеряют изменение тока датчика момента в возмущаемом канале, измеряют постоянную времени гироскопа и рассчитывают резонансную частоту по следующей формуле:где ωи ω- резонансная частота и измеренная частота вращения ротора, соответственно;C - осевой момент инерции ротора;τ - постоянная времени гироскопа, определяемая при измеренной частоте вращения ротора;K - полусумма угловых жесткостей торсионов по осям подвеса;ΔIи ΔI- изменение токов в датчике момента соответственно по оси возмущения и ей перпендикулярной;K, K- крутизна датчика момента по току в соответствующих осях.The method for determining the resonant frequency of a three-step gyroscope with an elastic suspension, including two correction channels and a moment sensor, consisting in the moment disturbance in one correction channel by introducing a constant voltage into this channel, measuring the change in the torque sensor current through a cross channel, and measuring the rotor speed, characterized in that, in order to increase the response speed of determining the resonant frequency, the change in the current of the torque sensor in the perturbed channel is measured, the time constant of the gyro is measured a and calculate the resonant frequency according to the following formula: where ω and ω are the resonant frequency and measured rotor speed, respectively, C is the axial moment of inertia of the rotor, τ is the gyroscope time constant, determined at the measured rotor speed, K is the half-sum of the angular torsions of the axes of suspension; ΔI and ΔI are the change in currents in the moment sensor, respectively, along the axis of perturbation and perpendicular to it; K, K is the steepness of the current sensor in current axes.
