Аннотация
A technique based on a discrete model of a vibratory process and an algorithm for calculating cumulative phases by means of a discrete Hilbert transform is developed. The digit capacity of an analog-to-digital converter and size of the sample for measurements of the phase difference of signals with error less than 0.001° are determined by numerical modeling. The performance of the proposed algorithm is confirmed using physical signals in the course of life tests of a damper made of a metal rubber wire material.
