Abstract: An experimental evaluation of a gas turbine/compressor train yielded excellent correlation between measured and predicted torsional critical speeds. Torsional strain signals acquired at a coupling ...

Abstract: Flow-induced vibration in safety relief valves (SRV’s) in high-energy piping systems such as power plants is identified as the source of many SRV failures. The mechanism is an unstable coupling ...

Abstract: This paper describes and discusses techniques that can effectively diagnose dynamics problems in turbomachinery. A variety of elusive dynamics problems are identified that require definition, ...

Abstract: Vibrations are often found to be the cause of rotating machinery failures. To minimize these outages a large number of vibration criteria have been introduced by technical societies, equipment ...

Abstract: This paper discusses development, installation, and analysis of instrumentation systems for reliably measuring casing, thermal distortion, and alignment deviation on a large combustion turbine in ...
