Ninety percent of all machines failures are signaled months, even years, in advance by changes in machine vibrations. Some failures are even predictable upon initial startup. By understanding a machine's vibration "signature", you can diagnose, solve, and prevent problems, as well as reduce the cost of maintenance. Machinery Vibration: Measurement and Analysis will show you how to use state-of-the-art instrumentation - transducers and fast Fourier transform (FFT) spectrum analyzers - to monitor machine conditions using the vibration signature. This expert sourcebook includes: Case histories that illustrate strategies for solving machinery problems - from imbalances and imbalances and misalignments to vortex flow and turbulence. A diagnostic chart for assessing the severity of vibrations. An overview of technology used in "trending" machine performance. guidelines for setting up a vibration monitoring system. Many illustrations throughout the book. Whether you're a plant or mechanical engineer, maintenance engineer, facility manager, mechanic, or technician, this book will unable you to troubleshoot mechanical problems and improve machinery performance.
