摘要

The results of development of the beam vibrating gyro equipped with special means of shock-resistant damping and elastic suspension of sensing element designed for operation in conditions of shock effects exceeding 20,000 g are presented in the paper. The various design concepts of elastic suspension of beam gyros ensuring effective "isolation" of sensing element from the basis are presented. It is shown that it is necessary to ensure the certain ratio between angular and linear stiffness both of suspension and beam to increase the accuracy of the vibrating gyro of a beam type. An engineering discrete model is offered in the paper on the basis of analysis of exact equations of a beam motion, which allows effective using the mathematical means of linear differential equations with constant factors to ensure a required control law at forming feedback loop in excitation plane. The model makes it possible to determine influence of a difference between natural frequencies and damping, which take place in planes of excitation and taking output, on the measurement range of input angular rate and also to calculate output characteristic of the gyro at the use of phase and amplitude ways of taking information (output). The characteristics of experimental samples of vibrating gyros of a beam type obtained at field shock test at the level > 20,000g are listed in the paper.
