Description
DIAGNOSIS OF FUNDAMENTAL FAULTS IN ROTATING MACHINERY P
Book Summary
This manual offers a practical and theoretical guide to fault diagnosis in rotating machinery through vibration analysis. Written by Beatriz Fraga de Cal and Pedro Fraga López, the book combines fundamentals of mechanical engineering with updated analysis methods, including the study of transient data during start-ups and shutdowns. Through mathematical models and practical cases, the reader will learn to identify faults such as shaft misalignment, rubs, fluid instability, and transverse cracks. An essential work for students and professionals looking to apply theory to real-world problems in predictive maintenance.
What is it about?
The book is structured into four key topics. First, it introduces the general theory of vibrations applied to rotating systems, establishing fundamental concepts. Then, it delves into modern techniques for vibration analysis and graphical presentation, with an emphasis on transient data obtained during start-ups and shutdowns, as well as the concept of damping or dynamic stiffness. The third topic develops mathematical models to analytically justify common faults such as misalignment, rotor-stator rubs, fluid instability, and transverse cracks, excluding mass unbalance due to its extensive existing bibliography. Finally, it applies this knowledge to practical cases, using a laboratory rotor and a hydraulic turbine as examples to quantify anomalies and demonstrate how the modification of dynamic stiffness is key to diagnosis.
Main Topics
- Vibration analysis in rotating systems
- Measurement and graphical presentation techniques for transient data
- Mathematical modeling of fundamental faults: misalignment, rubs, fluid instability, and transverse cracks
