dc.description.abstractother | The most important characteristics of inertial navigation systems based on accelerometers are the accuracy of determining their inertial speed and the coordinates of the carrier. In order to achieve high output data, it is necessary to take into account the features of the production of sensitive elements, threshold sensitivity, zero offset, nonlinearity, and other important indicators. To achieve the required parameters in linear accelerometers in order to achieve high performance in the manufacture of a sensitive element, it is necessary to develop a method of alignment of the linear accelerometer. The method of alignment of the linear accelerometer on the example of a precision pendulum accelerometer of compensatory type is offered in the article. For a pendulum in an elastic suspension in which its center of mass lies in a vertical plane passing through the axis of the suspension, the elastic moment is zero. In the circular rotation of such a pendulum relative to the horizontal axis of the perpendicular plane passing through the axis in the elastic suspension, the latter will not come out of this plane, and therefore, the signal of the angle sensor will not change. Thus, the adjustment of the sensing element of the accelerometer without feedback should include the following operations: Attending of the zero signal of the sensor in the vertical position of the axis of the PP, when there is no twisting of the elastic element and the elastic moment is zero; Balancing of the suspension, in the displacement of CM the pendulum (by changing the weight of the balancing load) with a vertical plane passing through the axis of the PP. To obtain the necessary ratios that determine the additional mass, the value of which must be changed during the alignment of the main load balancing, consider the accelerometer in two positions of the sensing element relative to the vertical position - in the position of the lower pendulum and in the position of the upper pendulum. | uk |
