Book Description
The purpose of this book is to serve as a reference text for the maintenance engineer and technician who is working with condition monitoring and predictive machinery maintenance technology. Broadly speaking, the subject is the principles of vibration theory and analysis as they apply to the determination of machine operating characteristics and deficiencies. The first chapter underscores the importance of vibration analysis in the field of predictive maintenance and root cause failure analysis.The chapters on vibration theory and frequency analysis lay the groundwork for the chapter on machine fault diagnostics based on vibration measurement and analysis. A systematic approach is used here to guide the reader through a logical sequence of steps to determine a machine's condition by detailed examination of vibration signatures.

Book Description
This book opens with an explanation of the vibrations of a single degree-of-freedom (dof) system for all beginners. Subsequently, vibration analysis of multi-dof systems is explained by modal analysis. Mode synthesis modeling is then introduced for system reduction, which aids understanding in a simplified manner of how complicated rotors behave. Rotor balancing techniques are offered for rigid and flexible rotors through several examples. Consideration of gyroscopic influences on the rotordynamics is then provided and vibration evaluation of a rotor-bearing system is emphasized in terms of forward and backward whirl rotor motions through eigenvalue (natural frequency and damping ratio) analysis. In addition to these rotordynamics concerning rotating shaft vibration measured in a stationary reference frame, blade vibrations are analyzed with Coriolis forces expressed in a rotating reference frame. Other phenomena that may be assessed in stationary and rotating reference frames include stability characteristics due to rotor internal damping and instabilities due to asymmetric shaft stiffness and thermal unbalance behavior.

Book Description
In order to identify unusual vibration occurrences and assess the general health of the test object, vibration analysis is a procedure that tracks vibration levels and looks into the patterns in vibration signals within a component, piece of equipment, or building. It is frequently conducted on both the frequency spectrum, which is derived by applying Fourier Transform to the time waveform, as well as the time waveforms of the vibration signal directly. Mechanical vibration Analysis should present 50% of any condition monitoring program. This book include a practical guide to vibration analysis to prepare practitioners for levels I II & III to become certified analyst. Numerous examples with photos are included to present how to detect different types of equipment and assets failure include: bearing, shafts misalignment, unbalance, rotor problems, electric motors and more using spectrum analysis technique.
