Description
пульса скорости определ ют масштабный коэффициент преобразовани датчика Кх- По другим координатным ос м калибровка осуществл етс аналогично.velocity pulses determine the scale conversion factor of the sensor Kx. On other coordinate axes, the calibration is carried out similarly.
После окончани времени измерени инерционный элемент возвращаетс в центральное положение, и процесс калибровки повтор етс , но импульс скорости задаетс трем другими индукторами И, И, Ие в направлении ОА, повернутом на 180° относительно направлени ОА.After the measurement time expires, the inertial element returns to the central position, and the calibration process repeats, but the speed pulse is set by three other inductors, AND, AND, IE, in the OA direction, rotated 180 ° relative to the OA direction.
Периодичность калибровки определ етс конкретными услови ми измерени .The calibration frequency is determined by the specific measurement conditions.
Предмет изобретени Subject invention
Способ калибровки акселерометра с ортогональными индукторами подвеса и со свободноCalibration method of accelerometer with orthogonal suspension inductors and with free
расположенным инерционным элементом, заключающийс в приложении воздействи заданной величины и измерении отклика, отличающийс тем, что, с целью исключени located inertial element, consisting in the application of the impact of a given magnitude and measurement of the response, characterized in that, in order to eliminate
вли ни внешних ускорений в услови х работы с пониженным ускорением силы т жести и сокращени времени калибровки, инерционному элементу в центральном положении сообщают индукторами подвеса эталонный поthe effect of external accelerations in working conditions with reduced acceleration of gravity and shortening the calibration time, the inertia element in the central position is reported by the suspension inductors
величине и направлению импульс скорости, измер ют датчиками смещение инерционного элемента по координатным ос м, сигнал смещени дважды дифференцируют, затем дважды интегрируют, вычитают из сигнала смещени полученный результат, затем повтор ют процесс калибровки, задава импульс скорости в направлении, измененном на 180°.the magnitude and direction of the velocity impulse, the sensors measure the displacement of the inertial element along the axes, the bias signal is twice differentiated, then twice integrated, the result is subtracted from the bias signal, then the calibration process is repeated, setting the speed pulse in the direction changed by 180 °.
