Abstract Utilizing shaft-speed information to analyse vibration signals is an important method for fault diagnosis and condition monitoring of rotating machineries, especially those running at variable speeds. However, in many cases, not always available, a variety reasons. Fortunately, most the measurements, embedded response different forms, such as format fundamental shaft-rotation-frequency...

Abstract Rotating shaft balances (RSBs) are devices that used to measure rotor blade forces and moments of wind tunnel models during tests. The design an RSB can be challenging, because it has comply with many sometimes contradicting requirements such as high stiffness strain gauge bridge outputs. manufacturing a conventional consists different subsequent steps, which time consuming, expensive ...
