Since the beginning of the second half of the last century pioneer researches on vibration-acoustic (acoustic in that time) diagnostics (VAD) of machinery in Russia have appeared. That applied scientific area has come a long and difficult way in development: gathering the experience, changing the conceptions, specifying the models, actively developing methods and means of analysis. The correlation between the role of the monitoring of vibration state and role of "Vibration condition monitoring", i.e. vibration-acoustic analysis has changed.
The rapid development of VAD in eighties of the last century was followed by a well-known period of decline in research & development. The result of that was deficit of the subject literature. Today, due to initiative and cooperation of Russian nondestructive testing (NDT) society, including more than 200 of Russian organizations, many manuals, monographs, and tutorials devoted to methods and means of NDT, technical diagnostics and monitoring were published. However, the scientific society impatiently waits for every new book, especially, on the VAD topics.
This tutorial presents VAD as component part of machinery condition monitoring and shows both general picture and methods of practical usage of the vibration monitoring and diagnostics methodology for detection of defects and malfunctions of machinery.
This tutorial briefly touches upon general issues of VAD methodology which are discussed in a sufficient number of monographs and reference books. To be the most valuable are considered the chapters about practical usage of vibration-acoustic signals for diagnosing and selecting diagnostic features of malfunctions with specification enough for using the provided information for detection of defects and malfunctions. The illustrations, on one hand, are showing the real episodes of condition monitoring and diagnostics of machinery, and, on the other hand, are generalized in the form of spectral masks which allows their practical appliance.
The tutorial is based not only on theoretical data, but, also, on great amount of author’s experience in research, implementation and operation of diagnostic and monitoring systems. It gives full and complete picture of theoretical and practical issues of VAD and monitoring of rotor and piston machines. The content of the tutorial corresponds to the global level of development of VAD and condition monitoring of machinery, and includes the chapters which not only provide knowledge on VAD and monitoring, but, also are useful methodological matter for calculation and analytical tasks, course papers and research projects.
The tutorial is the first comprehensive educational edition in Russian Federation in the field of vibration-acoustic analysis and monitoring of machinery, recommended for publishing by the Education and Methodics Association of higher education institutions of the Russian Federation for training in the field of construction and optics engineering for higher educational students of "Instrument-making" and made for students of the 200100 "Instrument-making" of Higher Professional Training 200102 specialty "Instruments and means of diagnostic and quality control", studying such disciplines as "Automated systems for quality control and diagnostics", "Methods of technical diagnostics", "Vibration monitoring" to become specialists, masters, bachelors, or training to become a vibration-analysis NDT method expert.
