Noise Diagnostics of Machines and Mechanisms

Goals

Determining the real position of the studied sample of the mechanism on its life cycle curve:

- residual life without failures under current operating conditions;

- forecast of failure and time of its occurrence under current operating conditions;

- recommendations for changing operating parameters in order to increase operating time without failure.

Required Source Data

An array (or a set of arrays) of signal records (time series) of the controlled parameters (characteristics) of the studied mechanism (machine) during operation.

It is highly desirable to provide data sets from the mechanisms of one model located at different stages of its life cycle.

Solution methods

The work on creating a diagnostic and monitoring system for a specific model of the mechanism is a project. The goals are achieved using flicker-noise spectroscopy technologies, modeling the phase space of the controlled parameters of the mechanism, and analyzing the stability properties of the motion trajectories in it. Work is divided into the following stages:

1. analysis of existing data (arrays) of control parameters of the mechanism or mechanisms of one model at different stages of the life cycle (which is preferable);
2. if necessary, develop a program of additional measurements and conduct these measurements;
3. analysis of the results, selection or modification of existing diagnostic techniques, the creation of algorithms and software, the creation of systems for collecting, analyzing information, the creation of decision-making systems.
