Ninety percent of all machine failures are signaled months, even years, in advance by changes in machine vibrations. Some future failures are even predictable upon initial start-up. 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, tranducers and fast Fourier transform (FFT) spectrum analyzers-to monito machine conditions using the vibration signature. This expert sourcebook includes:Case histories that illustrate strategies for solving machinery problems-from unblanaces and misalignments to vortex flow and turbulence.A diagnostic chart for assessing the severity of vibration.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 excellent book will enable you to troubleshoot mechanical problems and improve machinery performance.
