Mechanical Vibrations and Condition Monitoring pdf

Advertisement

Overview of Book :

Conditioning monitoring systems depend on the diagnosis of machinery, equipment, and machine trains. The principal source of data for the diagnosis comes from measuring mechanical vibrations. Traditionally, the study of the mechanical vibrations has been considered tedious work without an immediate application in engineering practice in the industry, but that could not be further from reality. The vibratory phenomenon is, practically, present in all machines and mechanical systems of any industrial facility or structure. The force that excites any structure comes from the movement of mechanical components. The variations in the homogeneity of the materials are among the causes of vibrations. Other sources of vibrations are the imperfections in the machining process, the manufacturing tolerances, and the clearance for assembly of the machines.

This book has two main objectives: To provide a maintenance engineer with the necessary tools to make proper use of his/her measuring equipment, and to introduce both engineering students and recently qualified engineers in the practical implementation of vibration analysis in the predictive maintenance of machinery. The mathematical developments highlight the principal concepts for understanding the theory, emphasizing the ideas of the vibration theory as well as their importance in the practice of predictive maintenance.
