Description for Development of an Ultrasonic Sensing Technique to Measure Lubricant Viscosity in Engine Journal Bearing in-Situ
hardcover. Series: Springer Theses. Num Pages: 167 pages, 75 black & white illustrations, 80 colour illustrations, biography. BIC Classification: TGBF; TGM; TGMT; TRC. Category: (P) Professional & Vocational. Dimension: 235 x 155. Weight in Grams: 444.
This thesis presents a novel ultrasonic instrument for non-invasive and in-situ characterization of journal bearing lubricant viscosity. In particular, the application to journal bearings is described by non-invasively measuring the viscosity and localized power losses throughout operation.
This ultrasonic viscometer is based on the reflection of polarized shear waves from a thin resonating coating layer to increase the measurement sensitivity, in comparison to conventional ultrasonic methods. This instrument allows for a full engine oil viscoelastic characterization in-situ.
The book investigates the effects of temperature, pressure and shear rate, and describes in detail the ultrasonic setup and method. Further, it demonstrates ... Read more
