Abstract. A way to realize the self-oscillatory operation mode of sensitive element in pendulous accelerometer with the use of a nonlinear unit of “ideal relay” type with a time delay is considered. Gain-phase characteristic of electromechanical component of the accelerometer and hodograph of the nonlinear unit are demonstrated. Necessary conditions for appearance of self-oscillatory mode of sensitive element operation are derived analytically. A block diagram of pendulous accelerometer with a nonlinear unit with delay is presented.
