Abstract

This paper presents selected problems connected with automation of procedures involved in assessment of machine degradation degree using vibration method with special emphasis on the machine state prognosis. The current knowledge of these problems is not sufficient and needs further research on data processing, analysis of efficiency of diagnostic and prognostic procedures, collection and selection of diagnostic parameters and development of automatic procedures for recognition and prognosis of a machine state. New solutions and different aspects of diagnostic prognosis based on the proposed partial procedures focus on factors determining automation of procedures for identification of technical systems states. New automated procedures for acquisition and processing of symptoms indicating the machine state provide better possibilities of control and supervision of technical systems operation and maintenance through identification of their current states, and its good prognosis.

Highlights

Increasing demand for methods and means of technical diagnostics, that is tools for assessment of technical systems degradation states, meets the needs of contemporary entrepreneurs who use a variety of technical appliances to run their businesses
Methods and means of modern technical diagnostics are tools for diagnosing states of technical systems which provides the basis for making operational decisions [4]
Technical diagnostics of mechanical engineering is based on utilization of information about the machine changes which enables identification of safety threats and progressing destruction of a machine throughout its life cycle

Summary

Introduction

Increasing demand for methods and means of technical diagnostics, that is tools for assessment of technical systems degradation states, meets the needs of contemporary entrepreneurs who use a variety of technical appliances to run their businesses. - access to advanced world technologies; - availability of the newest generation research equipment; - possibilities of the latest computer applications in the field of hardware and software; - access to databases, capital market and vast possibilities of cooperation All this have diametrically changed the views and achievements in automation of detection and control of technical object state changes by methods of technical diagnostics, especially in the field of shaping the current and predicted safety of technical objects. This provides the possibility of computerization of the processes connected with an object operation, supervision of the state changes, location of faults and minimization of damage effects and safety threats [12,21,24]. Computer aided modeling of an object lifetime, degradation processes, operation states, operation control and decision support systems – are the main issues to be addressed to provide technical systems with efficient operation
