TL;DR: In this article, a finite element model is used to calculate the response of a rotor with a propagating transverse crack under varying rotational speed conditions, and various order tracking techniques are implemented to remove the varying speed harmonic vibrations so that the non-order related vibrations in which information about the cracks are contained, are emphasized.

TL;DR: In this paper, the magnetic sensor is configured to sense a magnetic field about the shaft and provide an output representative of torque applied to the shaft, shaft rotational speed and shaft position.
Abstract: A sensor includes a shaft and a magnetic sensor. The shaft may have at least one magnetized active region. The magnetic sensor may be configured to sense a magnetic field about the shaft, and may provide an output representative of torque applied to the shaft, shaft rotational speed and shaft rotational position.

TL;DR: In this article, a rotating perforated plate with 1% open-area ratio was used to obtain the minimum fluidization velocity, Umf, and a decrease in Umf was observed when the rotational speed increases.

TL;DR: In this article, the effects of tangential speed and wear mechanism on the tribo-electrochemical characteristics of 316L stainless steel samples at each contact configuration were investigated using three contact configurations: two-body ceramic counterface (2B-CC), three-body rubber counterface(3B-RC), and three-bricheoric counterface, and the current was an increasing function of time even at constant rotational speed.

14 Oct 1994TL;DR: In this article, a diagnostic system is provided for detecting a fault condition in a transmission having a plurality of rotating components and clutches, and a transmission control, which includes speed sensors producing speed and direction signals representative of the rotational velocity of the rotating components.
Abstract: A diagnostic system is provided for detecting a fault condition in a transmission having a plurality of rotating components, a plurality of clutches, and a transmission control. The diagnostic system includes speed sensors producing speed and direction signals representative of the rotational velocity of the rotating components, a processor for calculating the relative rotational speed between two or more clutches and for indicating a fault condition in response to the relative rotational speed and a period of time.
