Vibration Problems in Machines: Diagnosis and Resolution [Hardcover]

Vibration Problems in Machines explains how to infer information about the internal operations of rotating machines from external measurements through methods used to resolve practical plant problems. Second edition includes summary of instrumentation, methods for establishing machine rundown data, relationship between the rundown curves and the ideal frequency response function. The section on balancing has been expanded and examples are given on the strategies for balancing a rotor with a bend, with new section on instabilities. It includes case studies with real plant data, MATLAB? scripts and functions for the modelling and analysis of rotating machines.1. Introduction. 2. Data Presentation. 3. Modeling and Analysis. 4.

Lees graduated in Physics and remained Manchester University for three years research. After completing his PhD , he joined the Central Electricity Generating Board, initially developing Finite Element codes then later resolving plant problems. After a sequence of positions he was appointed head of the Turbine Group for Nuclear Electric Plc. He moved to Swansea University in 1995 and has been active in both research and teaching. He is a regular reviewer of many technical journals and was, until his recent retirement, on the editorial boards of the Journal of Sound & Vibration and Communications on Numerical Methods in Engineering.
