Investigation of random processes in a double-integrating vibrational accelerometer

The dispersion of the slowly varying random process at the input of the nonlinear element of a double-integrating accelerometer as well as the statistical characteristics of the amplitude of self-oscillations of the instrument are studied on the basis of the equations of motion. The harmonic linearization method is used to investigate random processes in this nonlinear automatic system. It is found that the instrument under consideration is of sufficient sensitivity to measure accelerations of self-oscillatory type.
