... mode shape of piping vibration is identified by a transmission-type light emitting diode (LED) displacement sensor and the vibration stress is calculated based on beam theory using the approximated curve of the bending mode shape. The proposed method uses one advanced LED displacement sensor to measure...

...Nikola Jacimovic; Fabio D'Agaro Vibration-related issues are common in the engineering practice. Piping vibrations can range from those barely noticeable to the ones which result in total system failure in a very short time . This paper presents a synthesis of the criteria which should be used...

... the recommendations and lessons learned from these two failures. acoustic-induced fatigue piping vibration high gas velocity Piping systems of high gas velocity, exceeding 0.5 Mach, are susceptible to acoustic-induced fatigue. The susceptible areas are those coupled with high-pressure drop...
