Blade and Shaft Crack Detection Using Torsional Vibration Measurements Part 3: Field Application Demonstrations
The primary goal of the this paper is to summarize field demonstrations of the feasibility of detecting changes in blade and shaft natural frequencies (such as those associated with a blade or shaft crack) on operating machinery using non-contact, nonintrusive measurement methods. Laboratory demonstration of feasibility and some special signal processing issues were addressed in Parts 1 and 2 [...
متن کاملApplication of Torsional Vibration Measurement to Blade and Shaft Crack Detection in Operating Machinery
The primary goal of the this paper is to summarize field demonstrations of the feasibility of detecting changes in blade and shaft natural frequencies (such as those associated with a blade or shaft crack) on operating machinery using non-contact, nonintrusive measurement methods. This paper primarily addresses the results of application of this nonintrusive torsional vibration sensing to: a la...
متن کاملApplication of Torsional Vibration Measurement to Shaft Crack Monitoring in Power Plants
The primary goal of the this project was to demonstrate the feasibility of detecting changes in shaft natural frequencies (such as those associated with a shaft crack) on rotating machinery in electric power generation plants using non-contact, nonintrusive measurement methods. During the operation of power plant equipment, torsional natural frequencies are excited by turbulence, friction, and ...
متن کاملLateral and Longitudinal Vibration of a Rotating Flexible Beam Coupled with Torsional Vibration of a Flexible Shaft
In this study, rotating flexible shaft-disk system having flexible beams is considered as a dynamic system. After neglecting nonlinear terms, torsional vibration of the shaft-disk system and lateral and longitudinal vibration of the flexible beam are still coupled through the motor speed. The system has three natural frequencies; the flexible shaft-disk system torsional natural frequency, the f...
متن کاملCrack Detection of Timoshenko Beams Using Vibration Behavior and Neural Network
Abstract: In this research, at first, the natural frequencies of a cracked beam are obtained analytically, then, location and depth of a crack in beam is identified by neural network method. The research is applied on a beam with an open crack for three different boundary conditions. For this purpose, at first, the natural frequencies of the cracked beam are obtained analytically, to get the ex...
