Description

Изобретение относитс  к области гироскопического приборостроени . Известный способ определени  параметров системы коррекции гироскопического устройства , включающий нрилол- ение к гироскопу момента внешних сил, измерение скорости затухани  нутационных колебаний при включенной системе коррекции н вычисление параметров системы коррекции, плохо поддаетс  автоматизации и требует больших затрат времени. По предлагаемому способу дл  автоматизации и сокращени  времени контрол  параметров системы коррекции измер ют скорость затухани  нутационных колебаний при выключенной системе коррекции. Способ определени  параметров системы коррекции гироскопического устройства имеет следующую последовательность действий. К гироскопическому устройству прикладывают момент внешних сил, сообщающий гироскопу начальную скорость движени  относительно осей карданова подвеса. Приложенный момент вызывает возникновение нутационных колебаний гироскопа. Вследствие действи  на гироскоп сил трени  (диссипативные силы) нутационные колебани  затухают. Замер ют скорость затухани  нутационных колебаний, затем отключают систему коррекции гироскопического устройства и оп ть путем приложени  внешнего момента возбуждают нутационные колебани . Вновь измер ют скорость затухани  нутационных колебаний. Определ ют разность в скорости затухани  нутационных колебаний при включенной и выключенной системах коррекции и по известным формулам вычисл ют нараметры системы коррекции. Предмет изобретени  Снособ определени  параметров системы коррекции гироскопического устройства, включающий приложение к гироскопу момента внешних сил, измерение скорости затухани  нутационных колебаний при включенной системе коррекции и вычисление нараметров системы коррекции, отличающийс  тем, что, с целью автоматизации и сокращени  времени контрол  параметров системы коррекции, измер ют скорость затухани  нутационных колебаний при выключенной системе коррекции.This invention relates to the field of gyroscopic instrumentation. The well-known method for determining the parameters of a gyroscopic device correction system, which includes nulling the external forces to the gyroscope, measuring the attenuation rate of nutational oscillations when the correction system is turned on and calculating the parameters of the correction system, is difficult to automate and takes a lot of time. According to the proposed method for automating and reducing the time control of the parameters of the correction system, the attenuation rate of the nutation oscillations is measured with the correction system turned off. The method for determining the parameters of the gyroscopic correction system has the following sequence of actions. An external force moment is applied to the gyroscopic device, which informs the gyroscope of the initial speed of movement relative to the axes of the gimbals. The applied moment causes the occurrence of nutational oscillations of the gyroscope. Due to the effect of friction forces on the gyroscope (dissipative forces), nutational oscillations attenuate. The decay rate of the nutation oscillations is measured, then the gyroscopic device correction system is turned off and again, by applying an external moment, the nutation oscillations are excited. The attenuation rate of the nutation oscillations is measured again. The difference in the attenuation rate of the nutational oscillations is determined with the correction systems turned on and off and the known correction systems are calculated using known formulas. The subject of the invention is a method for determining the parameters of a gyroscopic device correction system, which includes applying a torque to a gyroscope, measuring the attenuation rate of nutational oscillations with the correction system turned on, and calculating the correction system parameters, characterized in that, in order to automate and reduce the time control parameters of the correction system Attenuation rate of nutation oscillations with the correction system turned off.
